1. a localization method, is applied to electronic equipment, it is characterized in that, comprising:

  • To base station transmission Location Request, receive the usable satellite list information of base station, and obtain prediction Navsat and report data, wherein, can obtain the gps time of the satellite in described usable satellite list according to described prediction Navsat report data;

    According to described usable satellite list, determine current satellite to be detected, and detect the gps navigation message that described current satellite to be detected is play;

    In the time receiving the described gps navigation message of designated length of described current detection satellite broadcasting, report data according to described prediction Navsat, determine corresponding first gps time of gps navigation message of described designated length;

    Utilize described the first gps time, calculate the pseudorange corresponding with described current satellite to be detected;

    In the time completing its computation of pseudoranges of usable satellite of specified quantity, determine the positional information of described electronic equipment according to the multiple pseudoranges that calculate.
