Abstract:
Provided is a positioning system which obtains mobile station positioning information indicating the current location of a mobile station, by using positioning signals received from a positioning satellite by a reference station and also by a mobile station installed in a moving machine, and is equipped with an automatic travel control means for executing automatic travel of the moving machine along a target travel route by using the mobile station positioning information, the positioning system being capable of accurate automatic travel along a target travel route even when the device itself constituting the reference station used in positioning at the time of automatic travel or the installation location of said device differs from that which was used in positioning when the target travel route was set. To this end, the positioning system is equipped with a reference station positioning means 43 for obtaining reference station positioning information indicating the current location of the reference station 4, by executing positioning based on a positioning signal received from a positioning satellite 3 and electronic reference point correction information obtained from an electronic reference point 5.
