Abstract
A method for a PC to realize an A-GPS in a PC technology field is provided. The method includes: a. the PC controlling a wireless network module of the PC to connect with a network to initiate a GPS positioning session; b. a location server transmitting GPS auxiliary information to the PC; c. the PC acquiring information of a current satellite according to the GPS auxiliary information. The method enables the A-GPS function to be applicable for the PC to provide positioning and navigation services to the PC. A corresponding A-GPS server can be connected to acquire the information of the current satellite based on the GPS auxiliary information with the network function provided by the wireless network module of the PC to accelerate the speed for acquiring data of the current satellite, and then current position information of the PC can be accurately calculated.
