• Verify that the receiver is in CPD base mode or in CPD rover
mode.
• Verify that the antenna connection is connected to the GPS
antenna. The GPS antenna must be mounted outdoors, with a
clear view of the sky. Nearby buildings and vegetation can
block the GPS signals or introduce multipath by reflecting
the GPS signals.
• Verify the receiver is computing autonomous position
properly.
• In the base receiver Verify the entered base station
coordinates as well, as described in next trouble shooting
In the rover receiver, verify the data link between the base and
rover/remote. In case of hardwired data link between receivers
from different vendors, check the hardware handshaking in the
RS-232 connection.
Base beeps • The entered coordinates differ from the computed
coordinates by more than 500 meters.
• Verify the receiver is computing autonomous position
properly.
• Verify and re-enter the coordinates or enter the raw position
as the base coordinates as described in “Base Position
Coordinates Selection: $PASHS,CPD,UBS” on page 60.
