3.4.16.2.2 Configuring General Configuration Parameters for the GPS
The GPS general configuration parameters determine how the GPS should
function with respect to the 4Motion system. Depending upon the values defined
for these parameters, you can configure the GPS clock (external 1PPS and
16MHz), and the UTC time. Run the following command to configure the global
configuration parameters for the GPS:
npu(config)# gps config ( [Type {Trimble | Lassen |
None}][HoldoverPassedTout <expiry_interval(0-2880)>]
[HoldoverPassTxOperationStop {Enable | Disable}][AlmanacUsableTime
<expiry_interval(0-4320)>] [EphemerisUsableTime
<expiry_interval(0-168)>] [IntervalToReadGPSTime{Hourly | Daily |
Monthly | Yearly}] [TimeToReadGPSTime <HH:MM:SS,DD/MM>]))
