30.4.1 Periodic
This is a periodic Location Reports sent by the terminal outside Emergency Mode.
While the terminal is not in Emergency Mode, and depending on the "Periodic" Trigger Enable
settings, it will acquire its position and send periodic Location Reports at intervals defined by the
GPS Idle Report Period (unless reports of that nature are inhibited, in which case it will do nothing).
Normal GPS periodic location reports are inhibited when the radio is in Emergency Mode. If GPS
periodic location reports are required during Emergency Mode, then it is necessary to enable the
Emergency Periodic reports.
30.4.2 Moved
At defined time intervals, the terminal checks its location against the last reported position, and
sends a Location Report whenever the check shows the position has changed by the specified
distance.
Note: A distance based location report is only sent if the distance between the measurement and
the last reported position is higher than the distance threshold. The real moved distance could
be higher (for example: coming back or going around the first point); also the change will not
be reported when its time elapsed is less than the preset time period.
30.4.3 Powered up
When the terminal is powered up, and subject to the "Powered up" Trigger Enable settings, it will
acquire its location and send a Location Report after performing the power up sequence.
