DR/GPS Receiver Modules GV-84H

DR/GPS Receiver Modules GV-84H

The Furuno GV-84H is the Hybrid DR(Dead Reckoning)/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

  • for Automotive/Industrial
  • for Consumer
The GV-84H is a DR(Dead Reckoning)/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)

GV-84H　EvaluationKit

GV-84H　EvaluationKit
GV-84H Evaluation Kit is available to evaluate the performance of GV-84H - the DR/GPS receiver module -.
The DR function is realized by built-in acceleration sensor and gyro sensor of the GPS module located at upper of the case.
FEATURES
  • ・Way of power supply can choose from USB bus power or an external power supply (5V DC).
  • ・The evaluation kit has two serial communication ports for external connection, which available for communication with the GPS Receiver.
  • ・Output data of the GPS receiver can be saved to SD card. (Insertion of SD card is needed.)
  • ・There are three LED indicators which show each operational state of the evaluation kit.
  • ・Outer size is (w) 152mm x (D) 105mm x (H) 24mm
  • ・Weight is about 452g.
  • ・Accessories are USB cable, Setting Stand and CD ROM containing the Communication Software, the USB driver and the documentations.
Field tests for two types of FURUNO GPS receiver modules that support dead reckoning navigation

Here, we are going to demonstrate the spot-on accuracy of the following two types of FURUNO's hybrid GPS receiver modules in comparison with the conventional standalone GPS positioning:
