Based on the TRK2000 the Trailer Tracker has been programmed to operate on a combination of GPS movement detection and a Movement Sensor in the unit.

The TRK2000 offers:
The Movement sensor wakes the unit up after 30 seconds of sustained movement. The unit will then continuously track the trailer until it sensors that movement has stopped, it will then record this as a stop.
If after 15 minutes there has been no movement the TRK2000TT will go into power save mode. In power save mode the unit will remain contactable for up to 20 days without charging (assuming a full charge at time of stop).
The TT can be wired into the running lights of a trailer. This enables the unit to recharge when the trailer is operating during night time long haul runs. The unit can also be wired to a 5W Solar panel or permanent power via a modification to the prime mover connection.
