How to reset the GPS clock

If the TCS is not reading the GPS, the letters "CPU" will be present in the upper left corner of the TCS screen, instead of the letters "GPS".  This may affect pointing.

First fix the GPS by cycling power, switching to the spare, or whatever.

The LED on the front should blink green at 1Hz.

Check the serial cable between the GPS and the TCS.

Reboot the TCS and reenter DUT by hand.

The DOS date and time should be checked at reboot and should be set as close as possible to the UT date and time.

Note that a Magellan1 GPS cannot be exchanged with a Magellan2 GPS.
