GPS/GNSS Modules

Multi-GNSS Receiver Module Model GN-87

Concurrent Multi-GNSS Receiver Module

GN-87 Modules provide the world’s most-accurate positioning and navigation solution using simultaneous Multi-GNSS technology in combination with active anti-jamming and advanced multipath mitigation.

Automotive/Industrial Consumer

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
  • Receivable Galileo E1B/E1C

    Galileo E1B and E1C signals receivable (ref. "Galileo OS SIS ICD Issue 1 Revision 1 September 2010")
  • Improved positioning rate with the world’s best-in-class number of acquired satellites

    • Twice the number of satellites in view than with GPS-only positioning thanks to Multi-GNSS
    • Improved success rate of positioning by receiving much more satellites even in urban canyons
    • Improved positioning accuracy in harsh environments where position jumps and misalignments occur with GPS-only positioning
  • 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
  • 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.
