Troubleshooting Guide

USB Installation failure

 Due to the nature of USB communications, the installation of the USB drivers may occasionally fail at various stages.

Should this happen the procedure should be repeated three or four times if necessary, prior to requesting technical support.

Trouble Locking onto Satellites

If the GPS engine under test is having trouble locking onto satellites when replaying recorded data then please follow the checklist below for typical solutions:

 During recording of LabSat data, ensure that the antenna is placed in a position where it has an unobstructed view of the sky. (See ‘GPS Antenna

Placement’ below)

 Check the antenna connection with the LabSat; only small amounts of dirt in the socket can cause a significant reduction in signal strength.

Also check the cable at the plug and along its length for any damage.

 Check that the power supply is connected and free from damage.

 If possible try another known working antenna, to confirm antenna functionality.

 Perform a GPS Cold start of the device under test after starting the replay of data. This is because a GPS receiver will normally download and store

almanac information to help it re-acquire satellite signals from power up. Therefore, when a recorded GPS test signal is replayed, it is possible that

any almanac data previously stored in the GPS engine will cause it to look for the wrong satellite signals.

No Communication with PC

 If the power LED on the front of the LabSat is not illuminated then there is no power to the unit; check that battery is fresh or, if using a cigar lighter,

check internal cigar lighter fuse.

 Check that the USB cable (A to B) is plugged into the ‘USB’ socket on the front panel of the LabSat.

 Try disconnecting then reconnecting the USB cable with the LabSat powered.

 Check that the USB cable is plugged into the COM port of the PC.

 Check that no other programs are using the same COM port.

 Disconnect the power to the LabSat then reconnect it.

COM Port Unavailable

 Another software package installed on your computer may have reserved the COM port. For example if VBOX Tools is open it may be using the COM

port, preventing the LabSat from using it.
