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 nationwide 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, to provide 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 through 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, which are arranged 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 the 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 users. ■ Users can achieve high-precision positioning based on the information sent from the Genoa Center. *For more details, please refer to the PDF document or feel free to contact us.
