Selection of Estonian Space Technologies 2024

Foreword

Estonian industrial enterprises and scientific research establishments have experience in the creation of space technologies and the development of space equipment for decades. Estonian membership in the European Union and in European Space Agency (ESA) has opened new avenues for businesses that have potential in space affairs. Moreover – operating in space affairs helps increase the influx of technology-intensive investments and improves the synchronicity of science and business, helping it to develop into an interdisciplinary field. Cooperation with ESA presents Estonian enterprises and scientific establishments with a unique opportunity to participate in ESA’s fast-moving technological development, with results that can also be implemented in Estonia. With the help of ESA optional programmes, we can support the development of the Estonian technology sector.

Cross-border cooperation is one of the most important preconditions for achieving the objectives set out in Estonian Space Policy and Programme 2020-2027 The main goal of the space policy and programme is to create an improved environment for Estonian technology companies and to increase their competitiveness. Estonia’s activities in the space domain will help our companies to integrate into the supply chains of major system integrators as well as facilitate the development of local integrators framework.

One of the main tasks of the mapping exercise at hand was to develop an understanding of the skills and competencies of the Estonian industry and how these skills could fit into the global space ecosystem. The information gathered will serve as an input to creating measures that are going to support the diffusion of technologies already used on Earth to space and vice versa.

The mapping exercise will continue, and new technology descriptions will be added when they occur. Further actions will be coordinated by the Estonian Space Office. We titled the document Estonian Space Directory to encourage readers to get in touch with their potential partners.

Introduction

Welcome to the Estonian Space Directory, where you can explore Estonia's growing capabilities in the space sector. Estonian space industry is rapidly expanding, and this directory serves as a guide to Estonian companies and organizations involved in the development of space technologies.

The Directory is divided into four main categories: Ground, Upstream, Downstream segments and R&D service providers. In the Ground segment, you will find companies and organizations involved in the construction and operation of ground-based infrastructure. The Upstream segment includes companies involved in the development and manufacturing of satellites and other space-related hardware. The Downstream segment includes companies and organizations focused on using space-based data. Finally, in the R&D service providers segment, you can find companies who offer technology development as a service.

Estonia's space industry has already achieved notable success, even though it is relatively young. Through this directory we aim to showcase the diverse range of capabilities within the industry. Whether you are a researcher, investor, simply curious about the exciting developments taking place in the Estonian space sector, or looking for business partnerships, the Estonian Space Directory is the perfect starting point for exploring the country's capabilities.

The document at hand is not a comprehensive overview of Estonian Space Technologies. However, it serves as a live document, which is updated periodically. We encourage Estonian space sector stakeholders who feel their technology descriptions could be included here, to get in touch with the Estonian Space Office and have their technologies included in the next revision of this document.

DETAILS

The Consultative Committee for Space Data Systems (CCSDS) is an international organization that supports collaboration and interoperability between member agencies through the establishment of space data and system standards. The goal of this technology development is to specify Mission Planning and Scheduling services in context of the CCSDS Mission Operations Services standard, and apply them in an operational context for validation and improvements. The activity started in 2013 as a PECS project and continued in 2018 through GSTP. As an outcome of the activity, CGI obtained a good overview of the mission planning domain through specification of the CCSDS MP services and development of a prototype external interface to ESA Mission Planning System Framework (MPSF) that implemented the MP services. In addition, CGI implemented the MP services in NanoSatMOFramework (NMF), the operating platform of ESA’s OPS-SAT mission. An OPS-SAT experiment was also developed that demonstrated on-board autonomy using the MP services. The purpose of the experiment was to enable autonomous, on-board decision making of an optical Earth observation satellite based on cloud cover.

KSI Blockchain — Global Signature and Verification Platform

KEY INFORMATION

KSI blockchain technology enables its customers to know and be able to forensically prove, whether any part of their systems or stored electronic data and logs have been changed, either by insiders, external actors, or technical malfunction. KSI blockchain provides a mathematically tamper-evident audit trail and evidence for post-incident investigations, establishing who, what and when with a forensic precision.

DETAILS

GUARDTIME guardtime.com

CONTACT

Kaarel Hanson Space Program Manager kaarel.hanson@guardtime.com

High-scale, high-frequency blockchain technology for real-time integrity instrumentation of systems, networks, processes and data. KSI blockchain allows to register and verify 1012 data items every second, with high availability (99,999%) and 100% data privacy guaranteed. KSI signatures are server based, meaning that signing data requires online access to the KSI service. The verification of the signatures can be done both offline and online. There are two options for access to KSI:

1) KSI Software Development Kit (SDK)

2) Catena middleware

The KSI SDK provides the lowest level of integration. It enables “full access” to the KSI functions (signing, extending, verifying) and lets the integrator fine-tune all possible options. As a consequence, it leaves many common challenges, such as signature storage and extension, to the integrator to solve.

Catena is middleware that is meant to address common integration challenges, such as asynchronous signing, signature persistence, and automatic extension. It provides the integrators with higher-level functionality, such as annotating signatures and linking signing events (data provenance), in order to reduce the effort for building a complete solution. Catena internally uses the aforementioned SDK to perform low-level KSI operations. The functionality of Catena is grouped and packaged into logical applications (Catena-KSI, Catena-DB, Catena-Prov) so that the integrator can choose which ones to deploy and use. KSI SDK and Catena are not mutually exclusive: they can be used in combination if needed. This depends on the application type and the requirements for signing and verifying data. Use-cases trusted audit trails: Space systems, from satellites to mission control centres, are frequently the target of cyberattacks.

Radio Frequency Reconnaissance and Countermeasures

KEY INFORMATION

Intelligent and automated C-UAS based on RF detection, Edge AI and jamming.

Figure: Rantelons drone detection system DTS-2458

DETAILS

RANTELON rantelon.ee

CONTACT

Rantelon develops technologies for detection, identification, and neutralization of commercial unmanned aircraft systems (UASs). Such UASs typically utilize the industrial, scientific, and medical (ISM) radio frequency (RF) bands for remotely controlling the UASs from a ground station. The developed counter unmanned system (C-UAS) technologies rely on detecting, identifying, and neutralizing those remote-control signals and also the signals that travel in the opposite direction, from the UAS to the ground station. In addition, Rantelon has integrated into the C-UAS systems the capabilities to prevent UASs from using different global navigation satellite systems (GNSSs) in order to prevent malicious UASs from carrying out pre-programmed missions while relying on GNSS for navigation.

Data management and artificial intelligence are key aspects of Rantelon’s C-UAS research and development efforts. That is because the principal challenge in detecting and identifying UASs using RF sensors is distinguishing between the different signal waveforms used by different UASs and other spectrum users that are not necessarily UASs. Artificial intelligence provides an efficient and accurate method for classifying between those different waveforms used by UASs and other spectrum users Indeed, AI based systems are outperforming classical identification systems in a wide range application. Data management and data gathering, on the other hand, allow to build the artificial intelligence models and attain necessary accuracy.

Continuing from the technology selection from detection and identification to destruction, RF based neutralization is and most probably will be one of the primary concepts in countering adversarial remotely controlled UASs. This encompasses simple denial-of-service attacks through jamming but also more complex approaches through spoofing.

Dynamic Pixel 3D cameras

KEY INFORMATION

LightCode Photonics is currently developing an innovative 3D imaging sensor which combines simple low-cost hardware with advanced statistical processing algorithms to achieve low-noise, high-resolution 3D measurements.

DETAILS

The dynamic pixel technology relies on the single pixel imaging concept. The computation load required to implement the dynamic pixel technology is lightweight and allows the camera’s hardware properties to be modified in software during its operation. The advantage of the technology lies in the ability to enhance the performance of existing direct time-of-flight array sensors to the levels attainable to the newest premium quality sensors with high native resolutions. The technology can also be combined with both affordable and accessible COTS (commercial off the shelf) sensors, and high-end, high-performance sensors available today.

Our hardware platform is easily configurable for implementation in various 3D-imaging use cases, such as short-range LiDAR, advanced driver-assistance systems (ADAS), stack height control, safeguarding minimum distances, object detection, collision avoidance for Autonomous Mobile Robots and Autonomous Delivery Vehicles. In addition, the solution can provide value to smart city applications. The applicability can also extend to space, e.g. docking and landing on other planets, providing vision for autonomous planetary rovers.

LightCode Photonics has started a collaboration project with ESA to validate technology suitability in space conditions.

LightCode Photonics is a science-intensive deep tech company developing breakthrough technology for smart machines.

We imagine a world, where routine work is automated and robots are handling tasks from city maintenance to parcel delivery, dangerous rescue missions and docking in space. Thus we are rethinking image acquisition and solving 3D imaging in a completely new way - via intelligent perception. LightCode Photonics is transforming 3D imaging from human-like perception to robotic vision - we are building the 3D camera using dynamic pixels.

Fuel Cells for Space Missions

PowerUP produces hydrogen fuel cell-based electric generators and proton exchange membrane (PEM) fuel cells. Its technology is used in sectors such as telecommunication, defence, construction, hospitals, and offgrid homes to name a few.

A fuel cell is a device that generates electricity by a chemical reaction, which requires hydrogen and oxygen. A single fuel cell generates a tiny amount of electricity, hence, cells are usually assembled into a stack.

Proton exchange membrane (PEM) fuel cells operate at a low temperature, which makes them suitable for homes, cars and other similar applications. Usually oxygen can be taken from surrounding air, but on Mars and Moon, there is no oxygen. Thereby, closed cathode technology is required. These fuel cells require oxygen to be supplied from a cylinder. PowerUP’s closed cathode fuel cells are lightweight and corrosionproof for use in Mars and Lunar cargo ships and rovers. The company has developed its own highly active bio-based and CO2-derived nanocatalyst. Industrial biowaste and CO2 are being used to synthesize a high surface area and highly porous nanocarbon supports which are further modified with metal nanoparticles. Closed cathode fuel cells are more efficient than open cathode fuel cells.

Stefano Alberico stefano@skudo.tech

Skudo is focusing on Cybersecurity solutions based on pure hardware encryption, rather than Software, as this guarantees the highest level of security for our customers. Our HSM (built within a single FPGA chip) is entirely verifiable by independent third parties. The FPGA chip is designed and implemented in Europe. While the Hardware Security Modules are widely available on the market and used in many applications, none of those chips can be verified to ensure they don’t contain any undocumented backdoors. This is where we differ from our competitors who have chosen “blind trust” towards the technology they propose.

For ESA we are currently working on a PoC which will have our encryption FPGA chip launched on a strato balloon to simulate a High Altitude Pseudo Satellite (HAPS conditions) and demonstrating an asymmetric encryption data link (fully deployed by a PKI) working at an altitude of 25 km in the stratosphere. One of the next steps will be to integrate our solution on a satellite and demonstrate our SDLS/TC/TM encryption technology in a real space environment where also the Operation Control Center will be involved.

In the past, we have demonstrated our encryption chip by integrating it with a commercial drone system while encrypting its wireless telemetry link (using the MAVlink protocol) between the flying drone and the Ground Control System.

For the consumer market we are launching a PCB device which offers our fully functional HSM chip (FPGA) for the makers community (RaspberryPi, Arduino, integrators, etc.) skudo.tech/kryptor

In the near future, we plan to develop and increase the number of available soft cores while migrating them also to other FPGA brands (e.g., space graded). We also aim to design and implement custom built solutions for mission critical applications based on our chip. Among those we want to target IoT, drones and space applications to start with.

Modern complex commercial off-the-shelf (COTS) electronics have various reliability concerns, in particular caused by aging and radiation effects which are especially pronounced in space applications due to high radiation and non-existent serviceability. It is therefore essential to manage the health of such electronic systems by closely monitoring the status of hardware resources and carefully planning their utilization. This allows to attain the highest possible performance using the remaining resources when some have already gone out of order. This is commonly referred to as graceful degradation. When these procedures are executed in the system itself, it becomes self-health-aware.

The health status is monitored either directly by embedded instrumentation for monitoring, the BuiltIn Self-Test procedure, etc., or indirectly via detected faults. The system maintains health statistics and generates a “health map” to avoid using faulty components and thus can continue working with somewhat reduced performance.

The concept of hierarchical cross-layer health management divides the self-health-awareness between the heterogeneous parts of the system according to the control hierarchy: the execution unit reports its health to a local controller which aggregates the data from several units and then in-turn, reports the status to the central controller higher in the hierarchy. Fault detection, information collection, analysis and scheduling/control decisions are commonly performed at different levels of the system: hardware, OS software, application software.

Asymmetric Encryption PKI

KEY INFORMATION

Design and implementation of a fully functional PKI architecture which is demonstrated by providing asymmetric encryption to a flying strato balloon simulating a vehicle in HAPS conditions (25 km of altitude).

Stefano Alberico stefano@skudo.tech

A fundamental feature of a public key encryption system, is that the party using a public key, usually does not know the corresponding private key. Instead, it relies on this being the ‘correct’ public key for its needs. We therefore refer to this party as the relying party. For the relying party to rely on a given public key for some purpose, it should be able to validate, with acceptable certainty, that this is the correct public key for the particular purpose and application. This is exactly the goal of the Public Key Infrastructure (PKI). PKI provides the infrastructure that allows a relying party to obtain a public key and validate that the public key fits its purpose. The PKI supports and allows the identification and authentication of various digital entities in the data network, by taking advantage of the use of digitally signed public certificates. Finally, once the parties are securely authenticated, it allows the safe exchange of data, e.g., avoiding MitM threats.

We are currently working on the PKI within the scope of a procurement contract signed with ESA where we aim to demonstrate this technology integrated on certain hardware equipment which is sent by a flying balloon to an altitude of 25 km (HAPS conditions). The flying vehicle will exchange encrypted data (SDLS/TC/TM links) with the ground control station by using the above mentioned PKI. All the encryption is executed within our Skudo’s HSM chip which runs within a single FPGA unit. The entire encryption architecture, the hardware controlling units (on the vehicle and on the ground) and the HSM chip are then integrated together with our own custom software developed ad-hoc for the demo project.

We plan to further improve the PKI architecture and integrate it with a real satellite vehicle (OPS-SAT) and with a ground OCC (ESOC) in order to provide a fully operational solution.

Combining the PKI with our HSM/FPGA and the SDLS/TC/TM protocols is a very unique solution which meets ESA future cybersecurity plans. At the moment, most missions (which use encryption) adopt a symmetric scheme and are forced to pre-share and upload the encryption keys to the satellite before every launch. The adoption of the PKI would allow not only to bypass this very unsecure step but also allow to re-key the satellite during the mission. It will also allow to provide a secure mechanism (though bi-directional authentication) for the remote update of mission-critical software operations.

High Accuracy Interferometer for Testing Optical Elements and Systems

KEY INFORMATION

High accuracy interferometer for testing shape and wave front quality of optical elements and systems. The interferometer D7 is proven for x-ray and semiconductor applications. Expansion is planned to space and other industries.

Traditional interferometers existing on the market use a special certified optical element as a reference for testing other optical elements.

Due to the growing complexity of forms and shapes of optical elements (e.g., aspheres and free-form mirrors for space telescopes) physical optical references became insufficient to achieve high level of accuracy.

To overcome this limit optics manufacturers use several metrology tools combining and averaging the results. Therefore, high accuracy measurements became time and cost intensive process.

Difrotec has developed the next generation interferometer D7 for testing any type of optics with accuracy 10-20 times exceeding competitive interferometers. Instead of using an interferometer and at least 3 or even 4 accessories like Zygo, Mahr-ESDI or QED do, Difrotec technology requires an interferometer and only 1 or 2 universal accessories which cover wide range of optical shapes. Previously Difrotec worked with US and Chinese customers who makes optics for x-ray and semiconductor applications. Now we move to test D7 for space and other not-optics related industries (e.g. automotive).

INTELLECTUAL PROPERTY

The D7 technology has patented in US (10247539) and Europe (EP318782). In addition to hardware Difrotec has developed analytical software for processing measurement results and moving from hardware sales to services and software. For this we need to expand our production capabilities and complete software development.

Optoelectronic oxygen sensors based on luminescence lifetime for measuring oxygen concentration from sub microbar to present atmospheric levels and above (depending on configuration).

The technology was originally developed at the Massachusetts Institute of Technology (MIT) for astrobiology and geobiology purposes (by Dr. Mihkel Pajusalu). The technology was licensed as open source and currently we are looking into commercial manufacturing in Estonia.

The technology is based on using a modulated light source to excite dye and measure its luminescence lifetime, which correlates with the amount of oxygen present. The main use of this is simulation experiments on ground for testing astrobiologically relevant scenarios and for verifying oxygen-free environments on ground. Technology could be modified for space use.

O2 Production on Mars from CO2

KEY INFORMATION

The Energy Technologies Laboratory is developing a technology to split CO2 into solid carbon and gaseous oxygen in molten salts to obtain breathable oxygen on Mars.

DETAILS

The atmosphere of Mars consists (by volume) over 95% of oxygen and carbon, elements that are crucial for human life. However, most of it is stuck in CO2, which is a very stable molecule and difficult to break.

Molten salt carbon capture and electrochemical transformation (MSCC-ET) is a technology where the CO2 molecule is broken up into solid carbon and molecular oxygen via a carbonate salt electrolyte. On earth, this technology has been touted to be the solution to the rising CO2 levels in the atmosphere. On Mars, it could be a solution to two problems: energy storage and oxygen production.

The carbon created on the cathode of the CO2 electrolyser could be burnt or re-oxidized afterwards in direct carbon fuel cell. In the literature, the charge efficiency of the deposition-oxidation of the carbon has been found to be up to 95%. On earth the deposition rate is limited by the low partial pressure of CO2, which is not a problem on Mars. On the anode side, one molecule of oxygen is created for each carbon atom added to the cathode product, which could be used to regenerate artificial air. A similar process is already in use by ESA to generate oxygen from moon regolith and in NASA’s MOXIE. A reactor technology is being developed, where solar power is used to drive the electrochemical splitting of CO2 into solid carbon and gaseous oxygen, which are then separated and stored. The issues that need to be solved are:

1) What is the efficiency of solid carbon storage and re-oxidation in Mars atmosphere under a voltage conceivably producible with solar panels,

2) What is the purity of the gaseous oxygen products in such a reactor, whether or not it can be used to regenerate artificial air and

3) If the relatively high temperatures needed for melting the electrolytes are achievable in a small reactor in Mars conditions.

MSCC-ET technology has the potential to provide oxygen for the regeneration of artificial air as well as a method for energy storage for space missions. Thus far a lot of the focus in the development of this technology has been on cheaply producing carbon nanomaterials, but other uses such as oxygen production and energy storage as carbon have been overlooked. The Energy Technologies Laboratory aims to study this process in a variety of atmospheres replicating conditions of space missions and to reduce the working temperature while increasing the energy efficiency.

Monograin Layer Solar Cell Technology for Space Application

KEY INFORMATION

The monograin layer solar cell (MGL) has a superstrata structure: Back foil/graphite/absorber/buffer/ZnO/ glass (or polymer film), where the absorber is a monolayer of nearly unisize, with a typical diameter of 40 µm, semiconductor powder crystals embedded into a layer of epoxy without contaminating the upper surfaces. CdS buffer layer is deposited onto the monograins by chemical bath deposition. The intrinsic ZnO and Al doped ZnO are deposited by RF sputtering. Solar cell structure is completed by vacuum evaporation of In grid contacts onto the ZnO window layer. Graphite paste is used to make the back contact.

The advantages of MGL solar cell technology are the following: (1) the absorber material monograins with single crystal`s optoelectronic properties could be obtained, (2) it is possible to achieve uniform distribution of elements due to high synthesis temperatures in the molten phase of flux where the material diffusion and transport processes are fast and therefore unwanted secondary phases can be avoided, (3) the material and the solar cell are prepared separately, enabling to perform post treatments only to the monograins, (4)the area and shape of the MGL solar modules with uniform properties is not limited, and (5) flexible cheap substrates can be used enabling versatile applications. Additionally, various semiconductors having photosensitivity could be used as an absorber in the MGL solar cell. Currently, MGL technology has proven to work well with semiconductors such as CuInSe2, CuInS2 , Cu2ZnSnS4 , Cu2ZnSnSe2 and their solid solutions Cu2ZnSn(SxSe1-x)4, also Cu(In,Ga)Se2, and CdTe. With ketserite materials Cu2ZnSnS4 and Cu2ZnSn(SxSe1-x)4, device performance close to the World record efficiencies in the field, are obtained.

Due to the advantages of MGL solar cell technology TalTech has been collaborating with ESA. ESA has shown remarkable interest to the technology for in-situ resource utilization in order to manufacture MGL solar cells from resources available on moon or other celestial body.

Kappazeta has developed an automated processing chain for Sentinel-1 satellite images to produce a time series for several parcel-related parameters. The calculated time series can be shared in various formats: e.g., database dump, .csv, through API, or through a custom requested format.

Which parameters and statistics can we calculate?

All parameters can be calculated over the area of a clients interest. We can provide:

- Coh VH, Coh VV - 6-day repeat pass interferometric coherence in VH and VV polarization

- VH/VV ratio - VH and VV polarization back-scatter ratio

- s0VH, s0VV - Calibrated and noise corrected back-scatter (sigma0) in VH and VV polarization

- Why our Sentinel-1 time series are the best on the market?

- Covering smaller parcels – we can reliably process 35 to 50% more parcels than other services on the market. Depending on the parcel shape we can go down to 0.5 ha parcels.

- Handling the noise correction professionally – compared to the output of common processing software, e.g., ESA SNAP, the parameters are less biased resulting in more accurate and reliable models.

- Solid performance for operational services – in 2017 we enabled the first country-wide mowing detection system (Estonia) and have kept it operational since then.

Where are time series from satellite data already used?

Sentinel-1 time series can improve models which are solely based on optical data. We have been using S1 data in machine learning models for agricultural insurance companies, including for crop yield prediction, damaged area delineation and field risk assessment. For carbon farming and afforestation projects we can create models to detect tree presence, crop type/rotation, cover crop and tillage events. Our time series together with machine learning algorithms are also used in nationwide systems for automated inspection of farmlands in Estonia and elsewhere for CAP monitoring and AMS systems.

DETAILS

Cloud can obscure optical satellite imagery, making consistent vegetation monitoring difficult. Depending on the area and season the gaps in time series can be longer than a month. This hinders downstream applications, such as detecting crop damage, yield map synthesis, and others that rely on a sufficiently dense series of NDVI images Cloud cover is especially problematic in the autumn, where cover persists for long periods

Thanks to our KappaMask cloudmask, we can accurately filter out cloud-covered areas in optical satellite imagery and refill the gaps wih AI-modeled NDVI using weather independent data radar satellite data.The backscatter of Synthetic Aperture Radar (SAR) data are useful for detecting crop cover over agricultural areas whilst the coherence could be inversely correlated to NDVI, making them complementary for interpolating missing NDVI data.

Cloduless sNDVI could be used as regular weather independent data product on its ownconstantly reflecting the status of the vegetation of an area of interest, it could also be as an input parameter for higher level agricultural services including for crop yield prediction, damaged area delineation and field risk assessment. Another useful application for agricultural paying agencies and/or farmers may be zoning or detecting fields and subfields which demonstrate homogenous or heterogenous growth.

Increasing grid capacity by 30% globally by 2030

KEY INFORMATION

It takes 10 years on average to build a high-voltage overhead line. The build-out of solar and wind is faster than our ability to build the grid. Insufficient transmission is now one of the biggest obstacles to cheap and clean energy.

Grid Raven helps use our existing grid assets to their maximum potential. Transmission overhead lines are extremely sensitive to wind: already a 2 m/s wind cools the conductors so effectively that twice the amount of energy can safely be transmitted. By properly accounting with the wind, it is possible to transmit on average 30% more power through the grid, globally.

Kaarel Hanson Space Program Manager kaarel.hanson@guardtime.com

SpaceGuard is a decentralised system for monitoring and managing space traffic coordination systems exchanging collision avoidance data between the involved entities in a secure and trusted way. These entities include operators, catalogue and conjunction data providers as well as service and/or supporting entities, such as expert centres. Such data exchange needs to comply with needs of the various actor roles, e.g. in terms of limiting data visibility to restricted collection of other entities, as well as ensure that data is unaltered during the communication process, and sending and the reception of messages is logged in a verifiable way. The communication between different parties is monitored, analysed and safeguarded for long-term verification.

Each message sent or received by an involved entity is cryptographically safeguarded using KSI, a blockchain-based time-stamping service designed and operated by Guardtime. This functionality is useful in resolving or even preventing some disputes between parties. Having cryptographic proof that data was sent and received by the intended recipient eliminates false claims that some data was not available or it was not presented in a timely manner. Safeguarding the communication channel is essential against false claims of unavailable connectivity. One party can not claim it was impossible to fulfil its obligations or respond to events due to unavailable communication.

Finally, SpaceGuard provides regulators a global situational awareness in the coordination domain by visualising all the data that has been collected, incuding active and historical events. This is a useful tool for conformity and compliance monitoring of space traffic coordination regulations.

ALUs Toolbox: Lightning-Fast Earth

Observation Data Processing Using GPU-s

KEY INFORMATION

The CGI Estonia Space & Earth Observation (EO) team has developed an open-source toolset for very fast generation of optical and radar EO data products.

DETAILS

The toolbox consists of software tools for very fast EO data processing on Graphical Processing Units (GPU-s). The tools are designed to work in processing infrastructures where both EO data and GPU-s have been made accessible for the software, and implement pre-processing routines for commonly used Optical and Synthetic Aperture Radar (SAR) EO data, allowing users more timely and convenient access to analysis-ready data without having to do manual pre-processing, that is conventionally a time -consuming activity. The use of GPU technology reduces the time, energy and costs spent on processing EO data by around an order of magnitude, smoothening user experience when doing on-demand processing and unlocking new application concepts that require fast generation of EO information.

The ALUs toolbox is in constant evolution, and new processing algorithms are added to the functionality. The latest version can be found on GitHub: https://github.com/cgiestonia-space/ALUs

The role of operator interfaces is to empower a human to solve a task with the help of a remote or co-located robot. We focus on developing and validating intuitive telerobotics operator interfaces for minimizing cognitive load to ensure fault tolerant and long-term autonomy. Intuitive telerobotic user experiences take advantage of all available communication modalities (e.g., speech, gestures and touch) as well as cultural and psychological profile of the intended user. To that end, we cover the full range of human-robot collaboration from human effortlessly controlling a robotic device to human assisting a highly-autonomous robotic agent. We are actively developing TeMoto, a software framework for adaptive and dependable robotic autonomy with dynamic resource management.

Our main areas of work include:

1) software framework for adaptive and dependable robotic autonomy for human-robot collaboration in high risk, high environment complexity and high level of autonomy.

2) designing human-robot interaction that leverages variable levels of autonomy, AI-driven motion planning, and augmented reality.

3) robot hardware and software platforms validating research results, showcasing technology readiness, and skilling the next generation of robotics engineers.

Potential use cases include:

+ teleoperation during planetary exploration;

+ teleoperation for system maintenance;

+ robotic assistants during manned missions.

DETAILS

The majority of the Earth’s rivers, lakes and glaciers remain unexplored due to the high cost and complexity of conducting direct field measurements. New, easy-to-use and cost-effective methods are required for the direct measurements of the physical conditions occurring in these key surface water bodies. In addition to satellite positioning and inertial measurements, bespoke sensing payloads (e.g., water quality) can also be integrated into the existing design as needed. The GNSS sensor can also be configured for atmospheric monitoring. Widely used in maritime applications, Lagrangian multisensory drifters have been successfully implemented for the study of large-scale flows in seas and oceans, but there exists a lack of a viable commercial technology for freshwater applications. Currently, there are no commercial competitors to this technology. Applications include monitoring remote rivers, lakes and coastal regions where the sensors can be airdropped from drones or light aircraft at heights of up to 300 m. We are currently looking for firms interested in licensing the technology for commercial uses. Targeted applications include measurement of flows in rivers during flood events to improve flood risk mapping, along coastal shore protection structures and harbours, in aquaculture facilities to provide real-time information on the sea state, and in lakes and reservoirs used for water supply and hydropower. Data from multiple sensors can also be used for passive identification and tracking of surface vessels, improving situational awareness in littoral operations. The multi-sensing drifters have been funded by the ETAg PUT grant 1690 “Bioinspired flow sensing”, and have been used in the Norwegian research project “MAMMAMIA” since 2019.

OMIs which are based on satellite and model data are used to track the vital health signs of the Baltic Sea and signals in line with climate change. The indicators include: Baltic Sea ice extent, temperature anomaly, temperature trends, etc.

Data can be downloaded from Copernicus Marine Environment Monitoring Service web site: marine.copernicus.eu/science-learning/ ocean-monitoring-indicators

Baltic Sea OMIs are calculated by the Baltic Sea Monitoring and Forecasting Centre (BAL MFC) which includes five leading operational oceanography centres around the Baltic Sea: Marine Systems Institute at Tallinn University of Technology (MSI), Bundesamt für Seeschifffahrt und Hydrographie (BSH), Danish Meteorological Institute (DMI), Finnish Meteorological Institute (FMI), Swedish Meteorological and Hydrological Institute (SMHI).

The methodology enables operational mapping of open water (including flood) and water under vegetation from Sentinel-1 imagery. The data processing set up also allows deriving statistical information about flood frequency inside the area of interest (defined area). Processing steps include automation downloading of EO data, pre-processing of Sentinel-1, raster based water mapping and post processing for filtering false alms (look-alikes). Testing showed the accuracy of the water mapping from Sentinel- 1 is 95%.

The development will provide operational and accurate sea ice charts and lake ice extent products to professional users and to the public in Estonia. Operational processing of the EO data ensures timely distribution of ice information via Web Map Service (WMS) and interactive webpage for public use (navigation, safety, tourism). The Estonian Environment Agency and IT Centre of the Ministry of the Environment are responsible for the routine operations of the ice monitoring service.

The Department of Marine Systems at Tallinn University of Technology and CGI Estonia are responsible for: (1) Development of the operational algorithms that enable to derive ice extent, type, concentration, thickness and snow cover from the Sentinel-1,-2 and-3 imagery; (2) The ICT modules which enable to archive the satellite sea ice products, deliver the products to expert users and distribute the ice info to general public via WMS service and web page.

The Estonian Weather Service is a national ice service in Estonia. During the winter navigation period, the Estonian Weather Service is responsible for providing daily ice reports (marine bulletin) and sea-ice charts over the exclusive economic zone and internal waters of Estonia. The operational sea ice service is based on a manual interpretation of satellite data and ground measurements.

The sea ice information is relevant for the transportation sector and ice breaking services as the accurate and timely information can reduce the fuel consumption of an ice breakers by 20%. The improved ice breaking service reduces the waiting time and atmospheric emission/ pollution of cargo vessels that in turn reduces the costs of vessel operators.

Secondly, the coastal and lake ice information provided by the service is relevant for safety reasons (permission to go on ice) and for planning re-creational activities, such as fishing and hiking on the ice. Moreover, in case of accidents (e.g., people on drift ice) the satellite data enables to carry out Search and Rescue missions on sea and lake ice.
