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 2):
The location system according to  claim 1 , wherein the at least one processor is further configured to:\n calculate a difference of arrival times of the radio signal between the fixed stations, calculate a difference between a carrier wave phase difference of the radio signal between the fixed stations and a carrier wave phase difference of the radio signal between the fixed stations in an immediately preceding posteriori period, and use the error reduction algorithm to increase reliability of the predicted arrival time of the radio signal in the following posteriori period, the arrival time being predicted from the difference of arrival times and the difference between the carrier wave phase differences.
