GV-87 GNSS Module With Dead Reckoning Support

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.


  • 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. Galileo Ready
  • Positioning available even in tunnels or underground parking. 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)
  • Emphasis on usability of Dead Reckoning, no need for sensor processing on host CPU
    •  Selectable from 3 different sensor configurations depending on customer’s product concept
    • 1. Gyro + Accelerometer 2. Gyro + Speed pulse 3. Wheel tick data of two non-turning wheels (Sensor-less)
    •  Autonomous, self-calibrating, tightly coupled Dead-Reckoning.
    •  Dead Reckoning calculation is performed on the module and the results outputted in NMEA data
  • 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
    •  Active Anti-Jamming
    •  Advanced Multipath Mitigation
  • Embedded Flash ROM
  • Suitable for long-term use backed by FURUNO’s continuous support and function enhancement
  • Suitable for Automotive Applications
  • Market’s standard size, superior design for assembly
    •  24Pin LCC (Leadless Chip Carrier)
    •  12.2mm x 16.0mm x 2.8mm
    •  Visible soldering condition with end-face electrodes
