GPS Receiver Module GV-84H

The Furuno GV-84H is the Hybrid DR/GPS receiver module equipped with the inertial gyro and acceleration sensors and a passive antenna.

GV-84H is available to use the dead reckoning function by itself, and accomplishes the hybrid positioning along with GPS

Features

  • The GV-84H is a DR/GPS module equipped with inertial sensors and the passive antenna.
  • High performance Dead Reckoning is realized thanks to the combination of GPS, Gyro sensor and acceleration sensor
  • High accuracy positioning is available in tunnels and urban canyons where GPS receivers cannot receive GPS signals
  • Designed specially for PND (Personal Navigation Device)
