GSOF message: Detail All SV
This message describes detailed satellite information for all tracked satellites in all tracked satellite systems. It contains the following data:
-
Number of satellites tracked
-
The PRN number of each satellite
-
The satellite system that the satellite belongs to
-
Flags indicating satellite status
-
Elevation above horizon, in degrees
-
Azimuth from True North, in degrees
-
Signal-to-noise ratio (SNR) of first frequency
-
Signal-to-noise ratio (SNR) of second frequency
-
Signal-to-noise ratio (SNR) of third frequency

PRN |
Char |
The PRN number of the satellite which the following flags refer to. This is the actual PRN number given by the SV (not ranged due to the SV system). |
||
SV System |
The system that the SV belongs to. Valid values are: 0: GPS |
