5.3.4 Improved (Take Location) Tracking Mode
This mode is based on the not-live-tracking mode and allows the unit to add and log
extra locations between transmissions. Since the entire system is hibernating most of
the time, the battery life is prolonged.
In this mode, the unit behaves as follows:
Checks power lines, button state changes, motion and MultiSenses (if programmed
to) once per second and logs them efficiently. Looks for distress (critical) events
(such as tamper, sensor reading crossed some predefined critical threshold) to
report them immediately.
Takes GNSS locations extra configurable times a day and logs them internally as
Type-0 and/or Type-11 with the same message but encapsulated.
GNSS and cellular modems are also activated upon distress event occurrences to
immediately report the position of the event. A transmission is sent even if the
GNSS has not got a fix after the timeout. If no fix is reached the Cell-ID
transmission logic is used.
The GNSS module is shut down, disregarding any applicative constraints to
preserve energy.
Turns on the cellular modem, at configurable times, and transmits the logged
messages, including the logged positions, measurements and events, to the
server.
For all cellular transmissions, the entire log memory is transferred/uploaded, and
then cleared upon an ACK from the server.
At all other times, the unit is sleeping (hibernating).
5.3.5 BOD/EOD Tracking Mode
CelloTrack 10y can be programmed to support the BOD (Beginning of Day)/EOD
(End of Day) Tracking mode.
This mode enables reporting on the leaving of the pick-up location (BOD) and arriving
to the destination location (EOD), supporting a minimal number of transmissions.
To support this mode, the unit maintains the BOD (BOD was recognized ) /EOD (EOD
was recognized) states; the last EOD location is also kept.
The unit uses the accelerometer for movement detection. The unit can be programmed
to communicate periodically with the MultiSense devices and log the sensor states.
The reporting policy of the BOD/EOD Tracking Mode is as follows:
Upon movement detection (short time) – start event is logged.
