AArdvArk dr+GPS key feAtureS when GPS Alone iS JuSt not Good enouGh The Trimble® Aardvark DR+GPS The Aardvark DR+GPS comes in two positions in deep urban canyons combines dead reckoning (DR) flavors: the -30 that must be flat with GPS to produce accurate and instantaneous positions, even under • Continuous position outputs in tunnels, parking garages and on lower bridge decks. • Reliable positioning for tracking the most difficult conditions. For service providers tracking highvalue or perishable cargo, Aardvark DR+GPS dramatically improves quality of service (QoS). Dead mapping applications. reckoning (DR) estimates position • Improves QoS and customer satisfaction and retention to maximize service revenue. • 19 mm x 19 mm SMT module • Provides DR data with 5Hz update frequency. 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. The -50 version contains a three axis gyro and sophisticated algorithms to self-calibrate. This allows the module to be mounted in any orientation on your vehicle and still output the highest quality position and velocity mea
