(2) Other settings
Other setting parameters of Rover include differential mode, data output
format and altitude cutoff angle etc..
Message format: Include RTCA, RTCM(2.X), RTCM(3.0), CMR, NovAtel
and sCMRx. If a Samsung system receiver is applied, the message format of
base station shall be set as sCMRx to support Beidou navigation differential
positioning. If a Beidou system RTK receiver is applied, the message format
of base station shall be set as RTCM(3.0) to transmit difference data.
Data output format: You can set up output data type and time interval for
GPS serial ports.
Altitude cutoff angle: Refers to the cutoff angle to receive satellite signals. It
can be adjusted in 5~20.
GGA transmission: When CORS network is connected, it is necessary to
report the Rover position to the computer host and obtain differential data
based on interpolation. If such network is utilized, select "GGA transmission"
as needed and choose transmission time interval. The default interval is "1s".
Start Glonass: Set whether to start up Glonass satellite system or not. When it
is selected, it means that Glonass satellite will take part in the resolving.
Conclusion of This Chapter
Serial port debugging is a very convenient tool with which you can send
commands to different types of HI-TARGET GPS and perform instrument
parameters setting.
This system will show different data debugging commands and parameter
settings interface automatically which match with corresponding different
instrument models connected.
