Course Objectives
This three-day course will give attendees a solid understanding of the key aspects of navigation, as applied specifically to portable devices. In particular, the course teaches GNSS basics, how GNSS receivers work, estimation algorithms and position computations, and integration of GNSS with other sensors, including inertial navigation systems. The inter-relatedness of these different aspects is also discussed. Ongoing challenges with the various technologies are taught to give attendees a practical understanding of what is possible and where more efforts may be needed.
Materials You Will Keep
A color electronic copy of all course notes will be provided on a USB Drive or CD-ROM. Bringing a laptop to this class is highly recommended for taking notes using the Adobe® Acrobat® sticky notes feature; power access will be provided. A black and white hard copy of the course notes will also be provided. (Note: Books, if any, for on-site group contracts are negotiated on a case by case basis.)
Who Should Attend
This course is for people working on various aspects of navigation systems for portable devices, but who want more exposure to the overall process. By better understanding the entire positioning problem and solution, attendees will gain an appreciation for how their work affects the overall system.
Prerequisites Because the course is designed to give an overview of several topics and how they interact within a portable navigation system, attendees do not need a background in any one particular area.
