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 autocalibrates these sensors and optimally blends the sensor inputs and GPS to produce accurate position and velocity outputs in the most hostile GPS environments. Lassen DR+GPS Technical Data Overview: DR positioning solution with integrated GPS receiver Available in kit and PCB module forms Supports both NMEA and Trimble binary protocols Automatic calibration of external sensor inputs Performance Characteristics : Position Update Rate: 1 Hz Horizontal Accuracy < 5 m Altitude Accuracy < 10 m Velocity Accuracy < 0.01 m/s PPS ± 500ns TTFF (calibrated) < 2 s Protocols : Configurable: NMEA or Trimble binary NMEA Messages GGA, VTG, GSA, GSV, ZDA and RMC Lassen DR+GPS Kit A Lassen DR+GPS module, gyro, backup battery and interface motherboard mounted in a rugged metal enclosure.
