Configure the Receiver in DGPS/RTK-
Base Mode
The receiver can generate and output DGPS and/or RTK corrections in the RTCM and CMR
formats. The list of supported RTCM and CMR messages can be found in appendix D.
1.6.1
Static Base Station Mode
To configure the receiver in static base station mode, the following has to be done:
1. For accurate and repetitive absolute positioning, you must provide the accurate
coordinates of the antenna reference point (ARP). The ARP usually corresponds to the
center of the bottom of the antenna (see also section 2.5). For example, assuming the
WGS84 position of the ARP is 50.5
o
N, 4
o
E and its altitude above the WGS84 ellipsoid is
100m, use:
setStaticPosGeodetic,Geodetic1,50.5,4,100 <CR>
setPVTMode,Static, ,Geodetic1 <CR>
If you are only interested in accurate determination of the base-rover baseline, with
the absolute position of the rover being of lesser importance, accurate positioning of
the base station is not required, and you may simply let the receiver determine its
fixed position autonomously ("auto-base" mode), by typing:
2. For RTCM 3.x, the antenna information in message types 1007, 1008 and 1033 can
be specified using the
command, with the serial number as
sixth argument, and the antenna type (called "antenna descriptor" in RTCM) as fifth
argument (see also section 2.5). For instance:
setAntennaOffset,Main, , , ,"AT2775-54SW","5684" <CR>
3. Use the commands
or
to specify the message interval (default is one
second for most messages). For instance, to change the interval at which RTCM 3.x
message type 1033 is generated to 10 seconds, type:
setRTCMv3Interval,RTCM1033,10 <CR>
4. Use the commands
or
to specify the base station ID. If you are setting up multiple base
stations, make sure to select a unique ID for each of them. For instance:
5. By default, the receiver is configured to output all RTCM and CMR messages necessary
for DGPS and RTK operation. If necessary, the set of output messages can be specified
with the commands
or
For instance, to output RTCM3.x messages 1006, 1033 and 1074 on COM2, use:
setRTCMv3Output,COM2,RRRTCM1074 <CR>
If you are using the RTCM3.x MSM messages (see appendix D), you can use the
command to configure the signal types that need to be
