Table 3-19: GPS Initialization/Verification

Step Action

1 To verify that Clock alarms (0000), Dpll is locked and has a reference source, and

GPS self test passed messages are displayed within the report, issue the following MMI

command

bstatus

– Observe the following typical response:

CSM Status INS:ACTIVE Slot A Clock MASTER.

BDC_MAP:000, This CSM’s BDC Map:0000

Clock Alarms (0000):

DPLL is locked and has a reference source.

GPS receiver self test result: passed

Time since reset 0:33:11, time since power on: 0:33:11

2 Enter the following command at the CSM> prompt to display the current status of the Loran and the

GPS receivers.

0 Local GPS Primary 4 Yes Good 3 0 Yes

HSO Backup 4 No N/A timed–out* Timed–out* No

*NOTE “Timed–out” should only be displayed while the HSO is warming up. “Not–Present” or

“Faulty” should not be displayed. If the HSO does not appear as one of the sources, then configure the

HSO as a back–up source by entering the following command at the CSM> prompt:

ss 1 12

After a maximum of 15 minutes, the Rubidium oscillator should reach operational temperature and the

LED on the HSO should now have changed from red to green. After the HSO front panel LED has

changed to green, enter

sources <cr> at the CSM> prompt. Verify that the HSO is now a valid

source by confirming that the bold text below matches the response of the “sources” command.

The HSO should be valid within one (1) minute, assuming the DPLL is locked and the HSO rubidium

oscillator is fully warmed.

Num Source Name Type TO Good Status Last Phase Target Phase Valid
