Configure Rover GPS Receiver to Function as an RTK Rover

This task is accomplished using the handheld computer running the field application
software. Configuring the rover receiver to function as an RTK rover as specified in
the following steps:
1. Set the receiver to RTK Rover mode
2. Inform the receiver which RS232 port the radio is connected to. This is the
port from which the rover receiver expects to see raw data from the base
system. If you followed the connection procedures above, the radio will be
connected to serial port B of the receiver.
3. Set the frequency on which the rover radio will listen for base transmissions.
In most cases, this will not change but it is recommended that the current
frequency is checked using the handheld computer. If using the spread-
spectrum radio, you are not required to select a frequency.
4. Inform the receiver if you want to collect raw data for post-processing.
In most cases, these are the only parameters that need to be set. There are other
more advanced parameters that can be changed, but normally the default values for
these parameters are sufficient. Following is a list of some of these more advanced
parameters:
• Raw data format - Sets the format in which raw data is being transmitted
by the base. Options are RTCM and PBEN (Ashtech proprietary). Default
is PBEN.
• Confidence level of RTK initialization - Sets the statistical confidence level
for RTK initialization. Options are 99% and 99.9%. Default is 99%.
Refer to the documentation for the field application software being used for
specific steps on how to configure the rover system with this software.

Verify Function

Perform the following observations to determine if the rover system is functioning
properly:
• Determine if the rover receiver is observing satellites. This can be
accomplished by either using the field application software running on the
handheld computer or the display on the receiver.
• Determine if the rover radio is receiving data from the base. This can be
accomplished by viewing the receive LED on the rover radio, which should
flash once every time the rover radio receives a packet of data. The
default transmission frequency by the base is 1 second. Therefore, the
transmit LED should flash once per second indicating proper reception of
