Document Type and Number:
WIPO Patent Application WO/2017/122253
Kind Code:
A1
Abstract:
A GPS correction data distribution device (10) is provided with a first communication unit (11) for communicating with a terminal device (20), a second communication unit (12) for communicating with a server (30), an HDD (14) for storing a database in which at least one coordinate and GPS correction data are correlated, and a management unit (16) for managing the database. The management unit (16) acquires GPS correction data from the server (30) for a coordinate in the database, correlates the coordinate and the GPS correction data, and updates the database. When a GPS correction data distribution request is received from the terminal device (20), the management unit (16) refers to the database and extracts GPS correction data of the coordinate corresponding to the position of the terminal device (20), and distributes the extracted GPS correction data to the terminal device (20).
