RTK Device & System

RTK Device & System Summary

IoT solution that can calculate 3cm ~ 50cm high position accuracy by calculating GPS data and correction information which is provided by reference station in real time

Feature

  • It has About 10 times higher accuracy than conventional GPS, and there is no shadow area by using LTE base station
  • We have a solution that minimizes the load on the system by utilizing an inexpensive commercial mobile network (LTE-Cat #1).
  • RTK device approximately 90% less expensive than other equipment
  • Depending on the service, Server-RTK solution or Device-RTK solution can be selected and applied.

System Configuration

Accurate location tracking IoT solution from 3cm to 50cm by calculating GPS data and calibration data in real time

  • Purpose

    Outdoor Positioning

  • Error

    Under 50cm (TTA Certi.)

  • Size

    7cm x 7cm x 3cm

  • component

    Built in MCU, Ant and GPS chip, LTE-M communication, LED and Speaker, USB Port

  • Server RTK method

    Receive the reference station correction value and GPS raw data of the terminal from the server, and process the data with the RTK Engine to send precise coordinates to the terminal.
    → It can save power consumption.

  • Device RTK method

    Receive the reference station correction value and GPS raw data of satellite directly from the terminal, and process the data with RTK S/W installed in the terminal to calculate the precise coordinate
    → The processing time is fast.
