GSOF message: Detail SV Info

This message describes detailed satellite information. It contains the following data:

  • Number of satellites tracked

  • The PRN number of each satellite

  • Flags indicating satellite status

  • Elevation above horizon, in degrees

  • Azimuth from True North, in degrees

  • Signal-to-noise ratio (SNR) of L1 signal

  • Signal-to-noise ratio (SNR) of L2 signal
