Time synchronization and positioning method and device, equipment and storage medium

The present application is applicable to the technical field of positioning, and provides a time synchronization and positioning method, apparatus and device, and a storage medium, applied to a first base station, the method comprising: receiving a first time signal sent by a terminal; receiving a second time signal forwarded by a second base station; calculating a delay inequality between the first base station and the second base station by using a least mean square adaptive filtering method; calculating a clock error between the first base station and the second base station according to the delay inequality between the first base station and the second base station; correcting the second time signal according to a clock error between the first base station and the second base station to obtain a true value of the second time signal; and calculating the coordinate value of the terminal according to the true values of the first time signal and the second time signal. According to the scheme, the delay inequ
