The WI-GPSDR-XX Embedded GPS & DR Module combines dead reckoning (DR) and GPS to produce accurate and instantaneous positions even under the most difficult conditions.The module allows OEMs to quickly and easily add reliable position tracking to vehicles carrying high-value or perishable cargo.

Powered by the Trimble Aardvark receiver, the Embedded GPS & DR Module features instantaneous and accurate performance in deep urban canyons and dense forests. The module uses dead reckoning (DR) to estimate position based on heading, distance traveled, and the last known position. The more accurate the speed, time and heading inputs, the more accurate the dead reckoning. Direction and Tachometer inputs allow the module to integrate with the vehicle systems. The GPS continuously calibrates the gyro and speed sensors to produce the most accurate position reading possible. Furthermore, the tri-axial gyro allows the module to be mounted in any orientation, simplifying the installation and calibration process normally required for a DR system.

The Embedded GPS & DR Module provides up to three interfaces to the host CPU, allowing OEMs to choose between USB, RS232, or UART. On-board status LEDs provide visual indicators for USB Activity and the GPS Pulse Per Second (PPS) signal. A high density, right angle connector also provides access to all signals allowing easy system integration. Furthermore, the module can be configured to receive power through the USB connector or an external system power source via a terminal block. A backup battery can also be attached which enables the GPS receiver to remain active in the event of main power failure, allowing a fast system recovery.

The WI-GPSDR-XX can be purchased Module only, with a Magnetic-Mount Antenna, a Compact Embedded Antenna, or a Bulkhead Antenna. A Development kit is also available allowing OEMs to quickly evaluate the module and its features.
