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

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)
