Saving a Receiver
Configuration
Saving the whole configuration of a receiver may be done
using the $PASHS,PAR,SAV command. The configuration is
saved as a PAR file, which is a binary file, and not an ASCII
file that would list all the $PASH commands relevant to the
receiver configuration.
The file naming convention used is the following:
PM_
Typically, the configuration will be saved on a USB key so that
later on you may possibly upload this configuration to another
of your receivers.
Connect the USB key as shown at the beginning of this
section before running the command from your data collector
or command terminal.
The configuration can alternately be saved to the internal
memory if necessary. For more information on the save
command, please refer to PAR,SAV: Saving the Receiver
Configuration To a PAR File on page
211.
Asking a Rover to Use the Same Local Coordinate System as the Base
In some applications, you may want your rover to deliver its
position in the same local coordinate as the one in which the
reference position of the base used is expressed.
This can be done by selecting the same local coordinate
system in the job open on rover side, but there is no guarantee
that the coordinate system you select in your job uses exactly
the same transformation parameters as the one used at the
base.
There is another more efficient and automatic process that
guarantees that the same coordinate transformation is used
on both sides, which is to ask the base to generate RTCM
messages 1021, 1022, 1023 and 1025 and enable the rover
to receive, decode and use them.
Using these messages, you can be certain that the rover will
use exactly the same local coordinate system as the base,
without any errors or discrepancies.
Implementing this function in the rover is simply made by
using the appropriate $PASHS,LCS command (see LCS:
Enabling/Disabling Use of Local Coordinate System on
page
192).
Once the function is enabled in the rover, and provided the
base generates these RTCM messages and the rover actually
