DOCOMO has a position information service that allows you to position the number of centimeters of errors in October-Komatsu will introduce

　On May 28, NTT DOCOMO provides 10 provisions of the "GNSS Location Information Distribution Base" that uses the satellite positioning system "GNSS (Global Navigation Satellite System)" to enable the number of centimeters of errors.It was announced that it will start on the 1st of the month.

　Komatsu has already been decided to use it in October, and expects to use it for use such as agriculture, car, and logistics.

Receive location information at the ground standard point and send correction information to the terminal

　The GNSS position correction information distribution platform is precise using signals from the location information satellite launched by major countries, such as GPS in the United States, GLONASS in Russia, Gallileo of EU, and Japan's quasi -top satellite system "Michibiki".A service that enables positioning.

　However, directly receiving GNSS signals will cause a large error.Therefore, the position is precisely positioned, the reference point to be installed on the ground and the fixed station receives signals from the satellite, processing the signal on the server, and using the DOCOMO mobile phone communication network for correction information.Send to to.The terminal receives a value indicating how far the terminal is from the server as a correction information and how far away the terminal is from the fixed station, calculates in conjunction with the location information received directly from the satellite, and derives the current location accurately.

　The technology has been performed in March with Komatsu and Light Huis Technology and Consulting in joint technical verification, and has succeeded in identifying the position with a plane and height of ± 2 cm.Due to the low price of GNSS -related devices, the use price can be reduced while providing location information with high accuracy.

　The standard point on the ground is the electronic standard point that the Geographical Survey Institute has already installed at about 1,300 locations nationwide.In order to further increase the accuracy, docomo will set up a fixed station on its own.DOCOMO states that the original fixed bureau is "listening to customer requests and installing from the necessary places. There are no special goals in setting a fixed station at this time."

In the future, the correction operation is also processed in the cloud

　Currently, the terminal has been implemented on the terminal that receives the correction information and calculates accurate positions, but DOCOMO has shown a concept in which this processing is also collectively processed with a server arranged in the cloud and mobile phone communication network in the future.This technology is developed by the NTT Research Institute as a "cloud GNSS position", and the period of practical use is "as soon as the research progresses" (NTT DOCOMO's Tani).If it is realized, the terminal will be able to grasp the accurate position simply by receiving the accurate location information that has been corrected.

　In the future, Mr. Tani said, "It may not require so much accuracy depending on the application, in such a case, we will provide services at a low price."Indicated that there is a possibility of providing at low cost.

　Komatsu, which has been decided to use the GNSS position correction information distribution platform from October 1st, provides a "Smart Contact Retro Fit Kit (tentative name)" that can be retrofitted to hydraulic shovels that have already been operated on site.Was revealed.The test will be introduced in October and will be released in April 2020.By using this kit, the hydraulic shovel allows you to grasp the accurate current location, saves the construction history in the cloud, and cooperates with the latest construction of Komatsu.

　Komatsu has been actively working on "i-constraction", which has long been reforming civil engineering sites with information and communication technology, and is an unmanned and automatically operating machine, and a service "Komtrax" that manages and controls its construction aircraft.We provide and so on.Mr. Hiroyuki Ogawa, CEO of Komatsu, said, "Approximately 98 % of the construction machinery operated on site have no automation function. It provides a retro fit kit there and coordinates the latest construction machine.By making it possible, we want to promote the automation of construction and contribute to the elimination of labor shortages due to population decline. "

　DOCOMO believes that the GNSS position correction information distribution base may be applied to various purposes, such as automatic driving cars, home delivery drones, and disaster predetictions, and the main use of "5G", which is characterized by low delay communication.He appealed that it could be one of the uses.
