RINQ GNSS Correctional Streaming Service

Product Summary

Suitable Industries:Construction Industry/Manufacturing Industry/Infrastructure Management

RINQ / RTCM Internet Neo Query is a cloud based GNSS Correction Service for HDT280. Access high accuracy single frequency RTK positioning from Base Station HDT280 for multiple rover stations.

Features

RINQ Main Features

  • Utilising private cloud servers to perform relative position calculation and measurement for centimetre level accuracy RTK-GNSS Positioning.
  • Simple set up requiring only a base station with HDT280 + Antenna and rover stations with HDT280 (Or a GNSS receiver) + Antenna
  • HDT280 Built in 3G/LTE Transceiver, no necessary third party extension required.
  • 1 HDT280 / 999 Rovers stations
  • Using HDT280 as Rovers allow for utilisation of 2 GNSS (GPS+GLONASS or GPS+BeiDou)
  • Correction Data Streaming is done though Akasaka Tec Cloud Service
  • NMEA0183 format Single Frequency RTK-GNSS Positional Data Output (Usable by HDT280)
  • Max 5Hz NMEA Sentences (GGA, GNS, GSA, GSV, RMC, VTG, ZDA) Output

※Accuracy and precision is affected by the baseline length
※Useable in 3G/LTE Covered Area

System Overview

RINQのシステム構成イメージ

Single Base Station for Many Rovers
Using only a single base station to send multiple correction data for a much more efficient system, especially when multiple rover stations are in operation at the same time.

Use Case Examples

Case 1: Construction Operation (e.g. SmartRoller)
RINQを工事現場で使う場合
GNSS correction data is streamed from a single HDT280 in base station mode to multiple rover stations within 10km radius of the base station via WEB.

Case 2: Train Tracking
RINQを列車運行で使う場合
Get the real-time position of trains to easily manage train timing safely and accurately.


Case 3: Airport Management (e.g. RTF300 RTK-GNSS Receivers)
RINQを空港で使う場合
Reduce the need for multiple base stations for automatic airport disembark gate and other operations.

Difference Compared to Traditional Network Based RTK-GNSS

  • RINQ offsets the base station and rover station bias.
  • It is possible to switch to BeiDou Correction Data by changing the settings on the Base Station
  • Viable into the future, by using BeiDou satellites, which provide services in east asia, south east asia and india with projected increase in satellites.
  • By using HTTP Protocol REST API, expandability of rover stations is easy.

Single Frequency RTK-GNSS Data

Compared to traditional single frequency positioning methods, RTK-GNSS have a shorter cold boot and calibration time, with a wider range of usable satellites comparable to traditional Dual-Frequency positioning for usability anytime anywhere.
