An information acquisition method. The method comprises: a first positioning device obtains a first satellite observation file of a mobile platform corresponding to a first operating task (S501), the first satellite observation file comprising a photographing timestamp of a mobile terminal and satellite observation data corresponding to the photographing timestamp; the first positioning device determines first operating time information corresponding to the first operating task (S502); the first positioning device automatically obtains a second satellite observation file corresponding to the first satellite observation file according to the first operating time information (S503), the second satellite observation file being a satellite observation file of a base station, the second satellite observation file and the first satellite observation file being used for calculating location information of a load of the mobile platform at the photographing timestamp, and the load being a photographing apparatus of the mobile platform. According to the method, the accuracy of obtaining satellite observation files is improved.
