frequency you plan to use. The second method is to observe the receive LED on the
rover radios. The base and rover radio will receive any traffic on the frequency they
are set to causing the receiver LED to flash. This is best done before setting up the
base system to transmit data. Any flashing of the receive LED indicates some traffic
on your frequency. If the base is transmitting data, the rover receive LED will flash
about once per second if receiving data from the base. If you observe more random
flashing of the receive LED, this is an indication of traffic on the frequency other than
the base transmissions.

1. Lower sensitivity of rover radio. The field application software packages let you
change the sensitivity of the rover radio, and you can also lower the sensitivity of
the PDL radio via the front panel display. Lower the sensitivity of the rover to
medium or low. If the traffic on your frequency is not strong in power, lowering the
sensitivity of the rover radio may cause the radio to ignore the traffic. This will not
help if the traffic is caused by a nearby or very high powered radio. The
disadvantage of lowering the sensitivity is a reduction in the range of your radio
system. A lower sensitivity at the rover may cause the rover to not hear the base
transmissions as the rover moves farther away from the base.
2. Try another frequency. If you are licensed to operate on more than one
frequency, move to a different frequency in hopes that the new frequency has less
traffic. If you have a license for only one frequency, you may need to find another
frequency in your area that is clear of traffic in order for the system to function
reliably and acquire a license for this frequency if possible.
Step 7. You may have a malfunctioning component in your system
Your rover radio or UHF Antenna Module may be malfunctioning. There is no way to
further isolate this problem unless you have spares for these components. Call your
local dealer or Thales Navigation technical support for assistance.

Rover System Is Not Computing A Position

Once the rover GPS receiver is set to function as an RTK rover, it will only compute
RTK quality positions. In order to accomplish this, the rover receiver must collect raw
satellite data at its position and also receive base satellite data transmitted by the
base system. Without these two components, the rover receiver will not compute a
position.
