AJ +S Advanced Jamming + Spoofing System Navigation is ever ywhere!

Space, or more precisely space technologies, have become a strategic field of operations, in times of peace and crisis, besides land, air, sea, and cyber The development of new as well as the modernization of existing Global Navigation Satellite Systems (GNSS), which started in recent years, illustrates this fact

Space technologies, -data, and -ser vices have become an essential part of the daily lives of European citizens, but safetycritical applications in the area of national defense and internal security also depend on these technologies However, the greater the dependence on Positioning, Navigation, and Timing (PNT), the greater the risk of unintentional and intentional disruptions and interference (jamming + spoofing). While jamming deliberately blocks the signal reception of GNSS receivers, spoofing aims to manipulate the position and time information of the attacked receiver This is of course enormously dangerous because the user thinks to be somewhere else than he actually is

Navigation Warfare

The goal of Navigation Warfare is the geographically limited disruption of (satellite-based) PNT information of an enemy while ensuring the resilience of the own systems.

However, since the use of GNSS and PNT will continue to increase in the future, it can be assumed that jamming and spoofing will also continue to increase Navigation Warfare would therefore also affect the use of navigation systems in the public domain and for each individual

Governmental authorities, armed forces, system integrators, and GNSS equipment manufacturers should be aware of the danger caused by GNSS signal jamming and spoofing. They should get the possibility to test their equipment in a protected and realistic environment to assess vulnerabilities and improve equipment in order to better tackle GNSS interference

AJ+S

OHB Digital Solutions has developed an Advanced Jamming + Spoofing (AJ+S) system that is able to assess the vulnerability of existing GNSS equipment and the performance of its countermeasures in a protected environment

• Mobile and sturdy system for navigation warfare scenarios in the field

• Easy to use system to test GNSS equipment against jamming + spoofing

• Covers a wide range of jamming and spoofing scenarios

• Supports synchronized attacks via built-in GNSS receiver

• Satellite data via built-in GNSS receiver or OHB’s assistance ser vice

AJ+S is able to generate and transmit jamming and spoofing signals but be aware that its use in public space is prohibited by the authorities

AJ+S is a mobile and sturdy 19" rack box, including:

• A user control unit (monitor, keyboard, and intuitive graphical user interface)

• A performant industrial-grade PC

• A signal generator with dual-channel high-fidelity RF output

• An integrated GNSS receiver for time synchronization and ephemeris data

• A broadcast antenna
