6.1.8 GPGST Pseudorange measurement noise statistics
This command is used to log pseudorange measurement noise statistics, these
values will be sent to the positioning results to present statistical qualities of the
positioning solution.
This log reflects the positioning accuracy of the “GPGGA”, except for the RMS field.
The RMS field, since it specifically relates to pseudorange inputs, does not represent
carrier-phase based positions.
Recommend Input:
Output 1Hz GPGST message from current serial port:
GPGST 1
Output 1Hz GPGST message from com2:
GPGST COM2 1
LOG output:
$GPGST,141451.00,1.18,0.00,0.00,0.0000,0.00,0.00,0.00*6B
