Introduction

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.

Key Features

  • Instantaneous and accurate positions in deep urban canyons and dense forests.
  • Continuous position outputs in tunnels, parking garages and on lower bridge decks.
  • Reliable positioning for tracking high-value assets and for mapping RF field strength.
  • Improves QoS and customer satisfaction and retention to maximize service revenue.

Lassen DR+GPS Module

A PCB assembly suitable for integration in navigation, telematics and tracking systems. This module includes a sophisticated DR processor and requires external inputs from a gyro, speed pulse, reverse indicator, and ignition indicator (see picture above for module).

Lassen DR+GPS Kit, front and rear viewsLassen DR+GPS Kit

A Lassen DR+GPS module, gyro, backup battery and interface motherboard mounted in a rugged metal enclosure. DR operation requires external connections to a speed pulse and forward/reverse signal.Picture to the right shows both the front and back of the unit, all interfaces are shown.

The kit includes:

  • Magnetic mount GPS antenna with 5m cable
  • USB interface cable
  • Vehicle interface cable
  • AC/DC power supply
  • Software toolkit and manual on CD-ROM

Under Windows, when connected to the PC via USB, the PC sees two COM ports which can be accessed via standard serial port software.
