2021/04/08 Trimble has introduced the Aardvark DR+GPS module that combines dead reckoning (DR) with GPS technology on a single, compact board. The Trimble Aardvark DR+GPS module provides positioning information when GPS signals are limited or not available, such as in urban canyons and tunnels. The Aardvark DR+GPS module is being marketed as a solution for system integrators or OEMs who are adding dead reckoning capabilities to vehicle navigation, fleet management and asset tracking systems. Dead reckoning 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. GPS contributes to accuracy by continuously calibrating the gyro and speed sensors to produce optimal dead reckoning. The 19 x 19 millimeter surface-mount module has an on-board gyro and collects speed and forward/reverse data from the vehicle’s sensors. Its DR+GPS algorithm automatically calibrates the gyro and external sensors’ inputs and blends this information with GPS measurements to produce accurate position and velocity outputs in hostile GPS environments such as urban canyons. The Aardvark DR+GPS module is available in two configurations: model number 88788-30 for flat installations; and model number 88788-50 with a feature supporting variable mounting installations. The 88788-50 self-determines the module’s orientation allowing the ultimate in installation flexibility.
