Cambridge Pixel Software
GPS Assist
Software that estimates vessel position from radar returns and terrain data to detect missing, spoofed or jammed GPS and provide backup navigation output.
Description
GPS Assist works with existing maritime radars on ships and uncrewed surface vessels as a safety backup. It estimates lat/long position by comparing radar data with predicted returns from terrain and coastline information in a database, and compares the result with the GPS-received position to detect missing, spoofed or jammed GPS signals. When such a condition is detected it can raise an alarm and generate its own NMEA-based navigation output, providing continuous navigation during GPS faults. Cambridge Pixel products are designed, developed and made in the UK and include 12 months of engineering support.
