AI Technical Summary
Technical Problem
The positioning device needs to re-acquire the ephemeris data after shutdown and restarting, which results in a long time in the positioning process and affects the positioning efficiency.
Method used
By comparing the first base station information before restart and the second base station information after restart, it is determined whether the device has moved. If no movement occurs, the first position information before restart is used to obtain the ephemeris data to reduce the acquisition time.
Benefits of technology
By reducing the time to acquire ephemeris data, the positioning efficiency of the positioning device is improved, and more accurately determine whether the device has moved.

Abstract
The invention provides a positioning method, system and device of a positioning device, a medium and a program product. The positioning method comprises the following steps: acquiring first base station information before the positioning equipment is restarted and second base station information after the positioning equipment is restarted; according to a comparison result of the first base station information and the second base station information, determining whether the positioning device moves before and after restarting; obtaining ephemeris data according to the first position information in response to the situation that the positioning equipment does not move, so as to reduce the ephemeris data obtaining duration; and second position information of the positioning equipment is calculated according to the ephemeris data. As the base station can stabilize the base station information, whether the positioning equipment moves or not can be more accurately determined according to the comparison result of the first base station information and the second base station information; if the first position information does not move, the ephemeris data can be acquired according to the first position information before restarting, so that the acquisition duration of the ephemeris data can be shortened, and the positioning efficiency of the positioning equipment can be improved.
