Troubleshooting
3. If the receiver is now powered up, go to step 2.
Step 2. Does the
Number of Tracked
Satellites Stay
Abnormally Low?
1. Check the information displayed on the receiver front
panel. In the upper line, starting from the left, the first
number displayed should gradually rise from 0 to 8 or
more. This information represents the number of tracked
satellites. In the same time, the last number in the same
line should increase as well, in the same proportion. This
information represents the number of satellites actually
used by the receiver, and should be equal to, or slightly
less than, the first number in the line.
2. If the receiver fails to track any satellites after a few
minutes of operation, see if you can improve this by
moving the receiver to a better place (a more open-sky
area) where there can’t be any doubt on the possibility for
a receiver to track satellites.
3. If the receiver still fails to track any satellites, a
component may be malfunctioning. Call your local dealer
or email Ashtech technical support for assistance.
Receiver is Not Logging Data
Raw Data Logging Icon: The Raw Data Logging icon on the front panel of the receiver
will be animated when data logging is in progress.
Examining the General Status screen, you determine that the
receiver is not logging data to memory. Follow the procedures
below to determine the cause of this problem.
Step 1. Has Data
Logging Been
Started?
At receiver power up, data logging is disabled in the receiver
(default setting). To start data logging, press the Log button
on the front panel, or use FAST Survey’s
Log Raw GPS function
from the Survey menu (tap the Start File button to start data
logging). By default, raw data is written to the receiver’s
internal memory.
1. If the Raw Data Logging icon starts blinking (animated
icon), then the problem is solved. Warning! The Raw Data
Logging icon may blink throughout a logging session, but
