NTT DoCoMo: Positioning formula car with an error of 10 cm: GNSS position information
NTT DoCoMo:
Demonstration at Suzuka:
On December 14, 2020, NTT DoCoMo conducted a demonstration experiment of a high-precision GNSS location information service.
It announced that it succeeded in positioning a formula car running at a maximum speed of 290 km / h with an error of 10 cm.
This will lead to the utilization of high-precision positioning technology in the automatic driving of automobiles and railways.
GNSS demonstration experiment:
The company announced that it has succeeded in positioning with an error of 10 cm in a formula car that runs at a maximum speed of 290 km / h.
High-precision GNSS location information service:
With the electronic reference point of the Geographical Survey Institute
Data observed by GNSS by DoCoMo’s own fixed station
It is collected in the position correction information distribution server and processed into position correction information.
DoCoMo’s original GNSS service:
It is a service that enables highly accurate positioning with an error of several centimeters by delivering it to mobile stations such as automobiles via a mobile phone network.
The error is smaller than GPS.
It is said that it can provide high value-added services.
19th JAF Suzuka Grand Prix:
The demonstration experiment was conducted at Suzuka Circuit from December 4th to 6th.
The GNSS antenna was mounted on the formula car, and the high-precision GNSS GNSS receiver was connected to the LTE line.
From the GNSS satellite and NTT DoCoMo position correction information server
Receives and analyzes position correction information data,
Real-time vehicle in the race.
It was confirmed that positioning can be performed with high accuracy.
Positioning with an error of 10 cm:
We compared the passing position of the beacon for lap time measurement installed in the circuit with the result of high-precision GNSS positioning.
As a result, it was found that “positioning can be performed with an error of about 10 cm”.
In addition, it was confirmed that “high-precision positioning is possible in 96% of the running time”.
