GSOF Messages B
SV Detail
This message provides 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
The following bytes are repeated for Number of SVs
PRN Char 01h-20h Pseudorandom number of satellites (1-32)
SV Flags1 Char See Table B.18 First set of satellite status bits
SV Flags2 Char See Table B.19 Second set of satellite status bits
