Step 9. You May Have A Malfunctioning Component In Your System; Rover System Is Not Computing A Position; Step 1. Is The Radio Receiving Data Transmitted By The Base - ashtech Z-Xtreme System Manual

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 9. You may have a malfunctioning component in your system

Your rover radio, radio antenna, or radio antenna cable may be
malfunctioning. There is no way to further isolate this problem unless you
have spares for these components. Call your local dealer or Ashtech
customer 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 it's position and also receive base satellite data transmitted by the
base system. Without these two components, the rover receiver will not compute a
position.
To determine if the rover system is computing a position, you can utilize either the dis-
play on the front panel or the field application software running on the handheld com-
puter. Refer to the appropriate documentation to determine how to perform this task.
Using either the receiver display or the application software, you have determined that
the rover system is not computing a position. Follow the steps outlined below to trou-
bleshoot this problem.

Step 1. Is the radio receiving data transmitted by the base?

To determine if the rover radio is receiving data from the base, examine the receive
LED on the radio. It should blink once every time it receives data transmitted by the
base. The default frequency of data transmission is once per second.
Not receiving data

System Troubleshooting above to troubleshoot this problem.
