settings used by your base station radio. For more information,
see Configuring input / output communication, page 59.
50.1 Configure base station output settings
Note – The Base Stn Config menu is available only when the Base
Station option is installed and a communication port is configured
correctly for it.
In Base Station mode, the receiver outputs RTCM (GPS correction)
data. The RTCM data can be transmitted to an external radio, which
then broadcasts the RTCM information to other DSM132 “rover”
receivers in the field that are within radio range. Generally, all rover
units are equipped with an identical radio which enables them to
receive the RTCM data from the base station radio.
The DSM 132 receiver has real-time capabilities, so a submeter
reference position can be created in seconds. Set the receiver antenna
over a known surveyed location, or allow the receiver to compute the
reference location. Once the reference position is supplied, the
receiver can begin computing PseudoRange correction information.
The information is converted to RTCM output data format. This
information is used to correct the rover’s final output position, and so
provides submeter accuracy.
50.2 Base location
You can use the Base Location screen to view the current location of
the receiver antenna. You can also use this screen to change the setting
for the location of the antenna. The screen provides the following
