Positioning system, positioning apparatus, positioning information providing apparatus, positioning method, control program for positioning system, and computer readable recording medium having recorded therein control program for positioning system
A positioning system is provided to set easily initial position information at a low cost without using a database in which positions of base stations are stored. A GPS server 200 has a server positioning section 210a that receives a position related signal transmitted by a GPS satellite to obtain data. A server-orbit-information acquiring program 232 analyzes the data to generate orbit information 262 and stores orbit information 262 in a server third storing unit 260 (ST30). A satellite-direction-information generating program 234 generates satellite direction information 264a, which includes an elevation angle and an azimuth angle of the GPS satellite viewed from a reference point (ST31). A generation-time-information generating program 236 acquires the time when the satellite direction information 264a is generated from a server clock section 218a and stores the time in the server third storing unit 260 (ST32).
