GPS ERROR

The GPS receiver is reporting an 
error.

If accompanied by the LOW CURRENT 
FAULT or HIGH CURRENT FAULT alarm, 
follow the recommended action for LOW 
CURRENT FAULT or HIGH CURRENT 
FAULT. 
If not accompanied by the LOW 
CURRENT FAULT or HIGH CURRENT 
FAULT alarm:
1. Remove the antenna cable from the 
connector panel on the shelf.
2. Measure the dc voltage from the 
antenna connector center pin to the 
connector housing on the shelf TNC 
antenna connector. 
3. If the voltage is not 18 Vdc ±2 Vdc, 
replace the TimeSource 3100 card using 
Procedure F.
4. If the voltage is 18 Vdc ±2 Vdc, 
measure the current between the antenna 
connector center pin and the connector 
housing on the shelf TNC antenna 
connector.
5. If the current is less than 5 mA or more 
than 500 mA, replace the TimeSource 
3100 card, using Procedure F. If not 
(nominal current is 125 mA, reconnect the 
antenna cable to the shelf.
6. Remove the antenna cable from the 
antenna, and measure dc voltage and 
current from the connector center pin to 
the connector housing on the cable 
connector.
7. If the readings are 18 Vdc and 125 mA, 
replace the antenna. If not, verify the 
cable path. Replace cables, lightning 
suppressor, or IF converter as necessary.
8. If the error repeats, check the view of 
the sky for obstructions.
9. If the error repeats, replace the 
antenna.
