MOVING-BODY POSITIONING DEVICE AND MOVING-BODY POSITIONING METHOD

WIPO Patent Application WO/2024/095512

A1

There is realized a moving-body positioning device that has a simple configuration, the moving-body positioning device assessing whether a mobile station is in a stationary state without relying on the detection accuracy of an inertia sensor. This moving-body positioning device 2 comprises: a satellite signal prediction unit 26 that calculates satellite signal prediction information 19, which includes a satellite signal 10 received by a mobile station 29 and a satellite-signal 10 prediction model that is to be distributed at a current time or in the future on the basis of a correction signal 11 based on the satellite signal 10 distributed from a base station 4; a satellite signal continuity assessment unit 27 that calculates satellite signal continuity information 16, which relates to the continuity of the satellite signal 10, on the basis of the satellite signal 10 and the satellite signal prediction information 19; and a computation control unit 28 that assesses whether the mobile station 29 is in a stationary state on the basis of the satellite signal continuity information 16. In cases in which continuity of the satellite signal 10 is detected on the basis of the satellite signal continuity information 16, the computation control unit 28 determines that the mobile station 29 is in a stationary state.
