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. Galileo Ready
  • 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
