2.7 RTK Configuration
Example of RTK configuration (base mode):
UNLOGALL
//remove all logs
UNDULATION USER 0.0 //
Set user specified undulation value for ellipsoid height
2
FIX POSITION B L H
//B: latitude (degree), L: longitude (degree), H: ellipsoid height (m)
For example: FIX POSITION xx.xxxxxx xx.xxxxxxx xx.xx
or POSAVE ON 0.02
//Turn on position average for 0.02 hour (72s)
LOG COM2 RTCM1006 ONTIME 10
//output the base coordinate
LOG COM2 RTCM1074 ONTIME 1
//output GPS observations
LOG COM2 RTCM1084 ONTIME 1
//output GLONASS observations
LOG COM2 RTCM1094 ONTIME 1
//output Galileo observations
LOG COM2 RTCM1114 ONTIME 1
//output QZSS observations
LOG COM2 RTCM1124 ONTIME 1
//output BeiDou observations
LOG COM2 RTCM1230 ONTIME 10
//output GLONASS bias information
LOG COM2 RTCM1033 ONTIME 10
//output antenna, receiver information
SAVECONFIG
//save the configuration above
Example of RTK configuration (rover mode):
UNLOGALL
//remove all logs
FIX NONE
//cancel the fixed coordinate of a base station
LOG GPGGA ONTIME 1
//output GPGGA to check position type
SAVECONFIG
//save the configuration above

The antenna of the base must be static and its position must be input,
several ways can be used to input the position of the base:
If the base's position is known, input it directly with command FIX.
