The Trimble® Aardvark DR+GPS combines dead reckoning (DR) with GPS to produce accurate and instantaneous positions, even under the most difficult conditions. For service providers tracking high-value or perishable cargo, Aardvark DR+GPS dramatically improves quality of service (QoS). Dead reckoning (DR) estimates position based on heading and distance traveled since the last known position. The more accurate the speed, time and heading inputs, the more accurate the dead reckoning. This is where GPS helps. GPS continuously calibrates the gyro and speed sensors to produce optimal dead reckoning. Aardvark DR+GPS has an on-board gyro sensor and accepts inputs from an odometer pulse and a forward/ reverse indicator. Its sophisticated DR+GPS algorithm autocalibrates these sensors and optimally blends the sensor inputs and GPS to produce accurate position and velocity outputs in the most hostile GPS environments.
