The GM-44DR Receiver combines new generation of concurrent GNSS solution and 3D automotive Dead Reckoning (ADR) technology. With 3D accelerometer, gyroscope sensor, and speed pulse input,GM-44DRdeliver continuous positioning for road vehicles during periods of signal loss such as in tunnels and parking garages.

The GM-44DR GNSS Receiver/ Smart Antenna has low profile, robust and waterproof enclosure with metallic bottom. It interfaces to a RS-232 serial comm. port of your computing device that utilizes NMEA 0183 GPS data output sentences.

The GM-44DR Locator is with high sensitivity and fast GNSS signal acquisition. In combination with speed information from the vehicle, the inertial navigation solution provides 100% coverage indoor/outdoor vehicle positioning during large multi-path related environments.

Features:

  • 100% indoor/outdoor vehicle positioning
  • 3-axis accelerometer and gyroscope sensor included
  • Metallic base to enhance the grounding



Applications:

  • GNSS navigation for 3D positioning
  • AVL applications
  • Inertial navigation
