DR/Multi-GNSS Receiver Module Model GV-87 Old Products (available)

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.



  • 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.
