Receiving, analyzing, and distributing real-time data released by the Geospatial Information Authority of Japan at the Genoa Center!
We will introduce the mechanism of network-based positioning. The Geospatial Information Authority of Japan operates a network of approximately 1,200 electronic reference points (GEONET) distributed across the country to monitor crustal deformation caused by earthquakes and volcanic activity, while also providing real-time data from these electronic reference points to the private sector. Our company receives this real-time data from the electronic reference points through the Japan Surveying Association, which is the distribution organization authorized by the Geospatial Information Authority, and conducts analysis 24 hours a day, 365 days a year, providing positioning correction data services to our customers. 【Features】 ■ Continuous monitoring of error factors 24 hours a day ■ Sending the approximate location of the surveying site to the Genoa Center ■ Distribution of correction information for relative positioning using virtual point and surface corrections ■ Obtaining high-precision location information with correction data *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Data Flow】 ■ At the Genoa Center, real-time observation data from electronic reference points deployed by the Geospatial Information Authority of Japan at intervals of several tens of kilometers is continuously received and analyzed 24 hours a day. → Information about the state of the ionosphere and troposphere above the area surrounded by electronic reference points, as well as satellite orbit information, is grasped. ■ Users send their approximate location (obtained through methods such as standalone positioning) to the Genoa Center via communication means such as mobile phones. ■ Based on the analyzed information about the ionosphere and other data, the Genoa Center calculates correction information based on the approximate location sent by the user. ■ Users can achieve high-precision positioning with the information sent from the Genoa Center. *For more details, please refer to the PDF document or feel free to contact us.
