GNSS for Automotive & Industrial

DR/Multi-GNSS Receiver Module

Model GV-87

Old Products

Dead Reckoning + Concurrent Multi-GNSS Receiver Module

*GV-87 is the exclusive product for the BOSCH SMI130 sensor users.
GV-87 is the concurrent Multi-GNSS Receiver Module supporting Dead Reckoning (DR) function, enabling high accuracy positioning with Multi-GNSS and also positioning in environments where no satellite signals are received.

Features

Multi-GNSS, Concurrent reception of GPS and GLONASS

The best positioning accuracy and smoothest ground tracking
Improved of robustness thanks to concurrent reception of GPS and GLONASS signals
Supports concurrent GPS, GLONASS, SBAS and QZSS.

Position available even in the tunnels, underground parking lots. Effective in urban canyons

Reduces degradation of position accuracy in harsh environments thanks to a combination of concurrent Multi-GNSS and Dead-Reckoning
Provides instant position at startup in underground parking lot type environments (Garage Start function)
Dead Reckoning positioning accuracy can be improved with feedback from the navigation application (Map Matching Feedback function)

Position accuracy of 2.5m (1σ) has been achieved in urban canyon

To improve the Dead Reckoning performance, it enables to keep high accuracy positiong even in very harsh environment

Emphasis on usability of Dead Reckoning, no need for sensor processing on host CPU

Autonomous, self-calibrating, tightly coupled Dead-Reckoning.
Dead Reckoning calculation is performed on the module and the results outputted in NMEA data

Link to the Smartphone(Apple CarPlay, Google Android Auto)

Ideal for the solutions to achieve highly-accurate Dead Reckoning positioning like car navigation system with CarPlay and Android Auto.
Try and see the performance of Dead Reckoning with Android Application connecting to the GV-87 Evaluation Kit VN-871.

Auto Orientation Function

Flexible installation with original axial correction

Sensors can be mounted sideways, on inclined surfaces, upside-down
Adapted for installation on inclined surface of the dashboards

Designed for real-life usage

Evaluates driving patterns under actual environment

Adapted for various cases causing large position errors such as “turn table”, “low-speed U-turn” etc.

Fast TTFF

Hot start: <1 sec

High Positioning Rate

Configurable position output update rate up to 10Hz (10 times per sec.)

Improved Noise Tolerance

Reduces effects of internal and external noise

Android™ driver and API

Furuno can provide Android driver and API, which can be used with Furuno's GNSS chip/module for Android application developers.
Android driver may help to reduce the development cost to install the GNSS chip/module in the navigation devices or the automotive devices based on Android.
