High-sensitive GPS Speedometer




LC-8310 High-sensitive 
GPS Speedometer




LC-8310 compact and high-sensitive GPS speedometer can measure speed, distance and other vehicle-related measurement items for two-wheel vehicles, or construction vehicles etc, by satellite signals of GPS/GLONASS and IMU.
You can set even on vehicles with limited installation space such as motorcycles and construction equipment as it is compact and lightweight unit.

The LC-8310 supports various needs of customers.




  • High precision measurement with satellite signals (GPS&GLONASS) and IMU
  • High precise measurement is enabled with Ono Sokki’s original technology. Depending on the situation, the proportion of each signal (GPS, GLONASS, and IMU) used is changed.
    Measurement performance: velocity accuracy of ±0.2 km/h, distance accuracy of ±0.2 %(300 m/h)

  • Various functions for vehicle tests
  • Analog output of velocity, pulse output of distance, 4ch analog input, 1ch pulse input, CAN communication, and various vehicle test functions (followed the previous model LC-8300)

  • Various functions easy to operate
  • USB memory provided as standard: Data can be transmitted and saved from the main unit to.
    Touch panel type LCD: easy to use and highly visible.
