Receiver problem

In rare occasions, the GPS receiver may require a reset to set the receiver to default values. The receiver must be placed in Test Mode to issue the GPS Reset command. Issue the GPS Reset command, RGPS, as shown below:

Type: TM ON <ent>
The unit will respond with a message stating Test Mode has been enabled. During Test Mode operation, the Major and Minor alarms are asserted.

Type: RGPS <ent>
After an approximate 10 second delay, the receiver responds with a reset status message. Allow 20 minutes for the receiver to begin tracking satellites.

Setting the current receiver position may assist in obtaining a satellite fix. To enter a new location, place the clock in Set Mode and issue the LOC command as follows:

Type: SM ON <ent>
Response: SET MODE = ON

Type: LOC [N:S] [DD MM SS.SSS][E:W] [DD MM SSS.SSS]<ent>
Where:

N = North Latitude
S = South Latitude
DD MM SS.SSS = Latitude Degrees:Minutes:Seconds
E = East Longitude
W = West Longitude
ddd mm ss.sss = Longitude Degrees:Minutes:Seconds

NOTE: The approximate location is adequate, zeros may be used for the seconds values.

Allow 20 minutes for the receiver to begin tracking satellites.
