B RINEX Files

The RINEX file format consists of three ASCII file types: observation data file, naviga-
tion message file and meteorological data file. The navigation RINEX files comprises
the Ephemeris information of all visible satellites at a control station or a commercial
receiver.
Each file type consists of a header section and a data section. The header section con-
tains global information for the entire file and is placed at the beginning of the file. The
format of the data records of the RINEX navigation message files may contain naviga-
tion messages of more than one satellite system (GPS, GLONASS, Galileo, etc.). See
