Abstract
A terminal device 50 includes aid-information acquisition device to acquire aid information 154 from an information providing apparatus, an information-providing-apparatus-sort judgment device to judge the type of information providing apparatus on the basis of positioning charge information 154a contained in the aid information 154, a positioning-basis-information generation device to generate positioning basis information 156 on the basis of position-relevant signals, a terminal-located-result-information generation device to locate a current position on the basis of the positioning basis information 156 to generate terminal-located position information and signal reception time information indicating signal reception times of the position-relevant signals, and a positioning-basis-information correction to correct the positioning basis information 156 on the basis of the signal reception time information to generate corrected positioning basis information 162.

2. A terminal device for communicating with an information providing apparatus providing aid information and determining a position location by receiving a position-relevant signal from a positional information satellite, the terminal device comprising:
-
an aid-information acquisition device being configured to acquire the aid information from the information providing apparatus;
a position-relevant-signal reception device being configured to receive the position-relevant signal from the positional information satellite on the basis of the aid information;
a positioning-basis-information generation device being configured to generate terminal-located position information by determining the position location of the terminal device on the basis of the position-relevant signal;
a corrected-positioning-basis-information transmission device being configured to generate and transmit corrected positioning basis information to the information providing apparatus on the basis of the terminal located position information and the position relevant signal, to acquire server-located position information indicative of a positional result on the basis of the corrected positioning basis information from the information providing apparatus, and to transmit the server-located position information, when the terminal device confirms that the information providing apparatus determines the position location on the basis of the aid information; and
a located-position-information transmission device being configured to transmit the terminal-located position information when the terminal device confirms that the information providing apparatus does not determine the position location on the basis of the aid information. - View Dependent Claims (3, 4)
