Abrégé
(EN)
The embodiment of the invention provides a cold start method and device for a GPS module of a terminal, the terminal and a storage medium. A satellite visible window table including ephemeris data records is preset. When the GPS module of the terminal is in cold start; the current target position information of the terminal can be obtained; directly selecting ephemeris data records of which the position information is matched with the target position information from a preset satellite visible window table according to the target position information to obtain a target record set. The method is advantaged in that according to the ephemeris data record in the target record set, N satellites greater than or equal to 4 are selected to form a visible satellite list, compared with the prior artthat ephemeris data is obtained in real time in a satellite orbit modeling mode during cold start, t the cold start time of the GPS module can be shortened, and the satisfaction degree of user experience is improved.
