Abstract:
A time of arrival t and a carrier wave phase ϕ of a positioning pulse that is transmitted from a mobile station in each posteriori period and that is received by each of at least three fixed stations are input. Then, by using an error reduction algorithm, a time of arrival t k+1  of the positioning pulse in the following posteriori period is predicted by using a carrier wave phase difference Δϕ of the positioning pulse. Then, by using the predicted time of arrival t of the positioning pulse, the location of the mobile station is calculated. A time interval dt of a posteriori period is set to a time interval with which a difference Δϕ nm  between the carrier wave phase differences, which is changed by the movement of the mobile station at an assumable maximum movement speed, is no greater than 180°.

Claim (Index 9):
The location system according to  claim 3 , wherein the predetermined time interval of the plurality of radio signals transmitted the plurality of times in each posteriori period is a time interval with which the difference between the carrier wave phase differences, which is changed during the predetermined time interval by movement of the mobile station, is no greater than 180\u00b0.
