Latitude (degrees). This is the latitude location of the GPS receiver. This is not a User
configurable parameter.
Longitude (degrees). This is the longitude location of the GPS receiver. This is not a User
configurable parameter.
Altitude (meters). This is the altitude in meters, above sea level of the GPS receiver. This is not a
User configurable parameter.
State. This is an indication of the state of the GPS receiver. This is not a User configurable
parameter.
Sync Loss Occurrences since Last Reboot. This is a cumulative count of the number of GPS sync
losses since the Base Station was last reset. This is not a User configurable parameter.
Sync Loss Recoveries since Last Reboot. This is a cumulative count of the number of GPS sync
recoveries since the Base Station was last reset. This is not a User configurable parameter.
The GPS will be in one of the states below from startup and until it is operational and providing
synchronization to the base station.
Offline. The 1 PPS from the satellite signal is not detected, so basic synch lock has not occurred.
This can be also seen as there should not be any coordinates if the GPS is “offline”
INIT: GPS state which dictates whether or not the BASE STATION will start transmission if the
GPS is enabled.
o INIT-Initializing
o INIT-Tracking-1-OSO
o INIT-Tracking-2-STO-Init
o INIT-Tracking-3-STO-Start
UP: GPS is operational (up).
o UP-Tracking-Done. Base Station will begin transmission
o UP-Tracking-Hist. Last GPS state indicating a steady state.
o UP-Holdoff
o UP-ReAcquire
o UP-Retrack
DOWN: GPS is not operational (down).
o DOWN-Unreliable
o DOWN-Recovery
3.5.3.5 Time Settings
It is important that the Base Station maintain an accurate date and time so that system logs are aligned
and may be correlated with other network activity and trouble reports. Although the date and time
must be initially set by the user, the Base Station supports the Network Time Protocol (NTP) to maintain
its accuracy. The use of NTP is optional
