DoCoMo: GNSS Position Correction Information, Distribution-Global Navigation Satellite System
NTT DoCoMo:
Positioning Satellite System With GNSS, positioning can be performed with a high accuracy of several centimeters.
Technical verification:
The project has been implemented since March 2019 and has achieved certain results.
Launched on October 1, 2019 (Tuesday) as “GNSS Position Correction Information Distribution Platform”.
Industry: IoT promotion
In each industry, the need for high accuracy location information is increasing.
In the construction machinery industry in particular, the spread of ICT construction machinery is an important issue.
Accurately grasping location information (in units of several centimeters) is essential for efficient construction management.
“GNSS Position Correction Information Distribution Platform”:
NTT DoCoMo’s fixed station stores GNSS observation position and correction data (GSI: 1,300 electronic reference point base) in the information distribution server.
By distributing the integrated processing position correction information to the mobile phone mobile station, high accuracy positioning of several centimeters in error is possible.
GNSS:
Global Navigation Satellite System.
A generic term for satellite positioning systems such as GPS, GLONASS, Galileo, and Quasi-Zenith Satellite (QZSS).
