About IntelliTrac A1-lite
The IntelliTrac A1-lite GPS Unit wirelessly transmits location, peripheral, and vehicle control data to
a control center. Location data, including speed, direction, mileage, and altitude, is provided by an
onboard GPS receiver. Wireless transmission is achieved using an onboard GSM/GPRS module. A
microcontroller is used to poll location and command data at regular intervals, derive actions based
on location, peripheral, and control data, and execute those actions.
One of the best feature of A series AVL is that they can transit data on ASCII mode or Binary mode.
Peripheral data indicates the status of the various peripherals that are connected to and/or
controlled by the unit. Peripherals include, but not limited to, door locks/un-locks , starter interrupt,
ignition, battery, engine and panic button.
Firmware on the device applies intelligent filtering to overcome coverage limitations for both GPS
and GSM/GPRS networks.
Motion sensor is used to control the status of the unit, either sleep, idle, or full power, there by
controlling the amount of current the unit consumes.
Backup battery and tamper sensing GPS Antennas are primarily used to indicate loss of Main
Power and loss of GPS antenna connectivity.
Device supports Over-the-air firmware upgrade to deliver added functionality without physically
touching the device once installed.
