GPS State
GPS State = NOT TRACKING: The GPS receiver is not tracking any satellites. This
condition may persist for some minutes after start-up. Detailed information on the GPS
receiver may be obtained from the status sri -t and status sri -gps commands. See the following
section for details.
GPS State = POSITION HOLD/GPS 3D FIX: This is the normal operating state of the
external/internal GPS receiver.
GPS State = SITE SURVEY: The GPS receiver will operate in this state for several hours
after an MTS is started in a new location for the first time. The GPS receiver is attempting
to determine accurate coordinates to enable operation in position hold.
GPS Satellites Tracked
GPS Satellites Tracked = <0.. 12>: This is the number of satellites
tracked that are available for timing.
If the status sri MMI command indicates that there are no satellites tracked,
then there may be a possible hardware fault. Refer to
Troubleshooting" on page 13-12
Sync Free Run Available
Sync Free Run Available (Minutes): This is the number of minutes that the MTS will operate
without any degradation of service if the GPS receiver stops working and the site reference is
configured for ASC operation. If the site reference is already in the free run state, the time
shown will be the balance of free run time before the MTS stops operating or switches to a
lower level of service.
Unsync Free Run Available (Days Hours Mins): This shows the amount of time the
sites 2nd level fallback (Unsynchronised free run) is capable of operating for. If the site
reference is already in Unsynchronised free run the time shown will be the amount of
time the MTS is capable of operating for before calibration is required.
Last Calibration Date Time
Last Calibration Date Time: The site reference will be periodically calibrated
whenever an adequate GPS signal is available. The MTS is capable of providing
service for up to 12 months without GPS after each calibration. This parameter
shows the date and time of the last calibration snapshot.
Calibration Due Date Time
Calibration Due Date Time: This shows the date where the MTS will need
calibration if the GPS receiver was to fail at this time.
GPS Time
UTC Time
Local Time
UTC Time Mode
UTC Time Mode = Not Precise or Precise: When the timing for the site reference is
being derived from the GPS receiver the UTC mode will be precise.
Synchronised
Synchronised = YES or NO: This indicates whether this MTS is capable of
operating synchronously with any neighboring MTS.
