Trimble Outdoors Part Number 45005-00-ENG manual Byte Bit Type Value Definition, Sv Prn

Trimble Standard Interface Protocol A

The next 5 bytes are repeated as a group for each satellite. The SV PRN and scale factor contains the SV PRN in the lower 5 bits, and the scale factor in the upper 3 bits. Range corrections are scaled by 0.02 meters times 2 raised to the scale factor power. Range-rate corrections are scaled by 0.002 meters per second times 2 raised to the scale factor power. The format is shown in Table A-61.
