Data Sheet

The Trimble® Lassen® 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, Lassen DR+GPS dramatically improves quality of service (QoS) and customer satisfaction and retention, helping tracking service providers to maximize revenue
opportunities.

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.  

Lassen DR+GPS accepts inputs from an analog gyro, an odometer pulse and a forward/reverse indicator. Its sophisticated DR+GPS algorithm auto-calibrates these sensors and optimally blends the sensor inputs and GPS to produce accurate position and velocity
outputs in the most hostile GPS environments.

Antennas
The Lassen DR+GPS module is compatible with active compact and non magnetic antennas suitable for vehicle installations.
