RinexNavFile Object

Top  Previous  Next


The RinexNavFile object provides functionalities for reading and writing Broadcast Ephemeris data to and from a Rinex Navigation file.  This is an ASCII file of GPS Broadcast Ephemeris data conforming to the RINEX standard.


RinexNavFiles (also known as GPS Broadcast Ephemerides) contain position, velocity, and clock information for all the satellites of the GPS constellation.  FreeFlyer has the ability to read and write RinexNavFiles, but does not generate Broadcast Ephemeris data when propagating spacecraft.  The time system is GPS Time, and positions and velocities are in the ECEF reference frame, which FreeFlyer converts into the MJ2000 frame.
