4. Check quality of electrical power supplied to PCS.
5. Check PCS connection to ground through ground strap to grounding screw or stud on PCS rear
panel.
6. If failure still exists, system may have experienced a board failure. Substitute working PCS for
failed unit.
Return the failed PCS to Applanix for repair. Provide a report of your findings with the returned PCS,
refer to Technical Support and Service on page A-1.
Initialization Failure
The system Initialization procedure requires POS MV to compute the approximate tilt of the IMU relative
to a locally level reference, taking into account the present position. This is called coarse levelling. If POS
MV fails to complete its coarse levelling procedure, the most likely cause is the lack of GNSS aiding data.
If the system fails to complete coarse levelling, follow the instructions below to isolate the problem:
1. Check Nav Status on controller main window.
2. If Nav Status shows DR (Dead Reckoning), select View, GNSS Data from the controller menu
bar, see Figure 73. If Receiver Status Mode indicates No Nav Data follow GNSS Not Available
procedure starting on page 9-28.
3. Check IMU Status on controller main window. If IMU Status shows Failure or Warning, power-
off system and contact Applanix for instructions to return IMU for repair.
