Introduction
GEONET (GPS geologic observation network) is the national GPS network of Japan with 1,200 permanent GPS stations, which is currently the largest GPS network in the world.
This network was created by the Geographic Organization of Japan with the aim of determining the changes in the Crust’s shape and geodetic control. In order to accelerate the process of monitoring the Crust’s shape changes and add this task as a social infrastructure to instant positioning services and other applications, the ability to instantly determine the position is also added to this network.
In this paper, we briefly discuss the network’s history, system, applications and future outlook.
