GPS Protection Level

Application for the computation of GPS protection levels from navigation messages or almanacs.

This application consists of a graphical user interface dedicated to the computation and the representation of GPS protection levels, set in terms of:

• GPS almanacs, satellite URA, Klobuchar coefficients or navigation messages,
• Time (UTC date and hour),
• Position (latitude, longitude and altitude),
• Probabilities (false alarm and missed detection probabilities).

The application is compliant with almanacs (YUMA-format) and navigation messages (RINEX type N) from:

• CELESTRAK: https://celestrak.org/GPS/almanac/Yuma,
• NAVCEN: https://www.navcen.uscg.gov/sites/default/files/gps/almanac/current_yuma.alm,
• NASA CDDIS: https://urs.earthdata.nasa.gov/.
