RTK Base/Rover Setup Using CMR

The following configuration will set up a base station and remote rover for RTK using the CMR differential correction format. These setups assume radio modems are connected to COM2 on both GPS receivers. 

Commands should be entered using COM1. The GPS receiver will lose the configuration when power is cycled to the unit, or if the GPS receiver is reset for any reason. If you want to make the GPS receiver remember these settings you can use the SAVECONFIG command to save the configuration to NVRAM. 

Base Station: 
=========== 
FIX POSITION lat long hgt (hgt is geoid/MSL height) 
LOG COM2 CMROBS ONTIME 1 
LOG COM2 CMRREF ONTIME 10 
LOG COM2 CMRDESC ONTIME 10,5 (optional, provides "type 2" CMR corrections) 
COM COM2 9600 N 8 1 N OFF 
INTERFACEMODE COM2 NONE CMR OFF 
SAVECONFIG (optional) 

Remote Rover: 
============ 
COM COM2 9600 N 8 1 N OFF 
INTERFACEMODE COM2 CMR NONE OFF 
LOG COM1 BESTPOSA ONTIME 1 (optional, but lets you monitor the position type) 
SAVECONFIG (optional) 

There is currently no pseudo-differential option supported under the CMR format.
