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.
