Beschreibung
Zusammenfassung:	GPS (Global Positioning System) correction data distribution device includes: first communicator that communicates with terminal device; second communicator that communicates with server; HDD (hard drive) that stores a database, the database having at least one coordinate and GPS correction data in association with each other; and manager that manages the database. Manager obtains GPS correction data from server with respect to the coordinate in the database, and updates the database while associating the coordinate with the GPS correction data. Manager refers to the database upon receipt of the GPS correction data distribution request from terminal device, extracts the GPS correction data of the coordinate corresponding to a position of the terminal device, and distributes the extracted GPS correction data to terminal device.
