Patent ID: 7292938

Claim:
A position locating system comprising: a terminal device being configured to acquire a located result of a current position based on position-relevant signals from positional information satellites; and a plurality of various information providing apparatuses being configured to provide aid information to said terminal device, said aid information including positioning charge information being configured to indicate whether or not an information providing apparatus of said plurality of various information providing apparatuses indicates a current position, said terminal device including, an aid-information acquisition device being configured to acquire said aid information from said information providing apparatus, an information-providing-apparatus-sort judgment device being configured to judge the type of said information providing apparatus on the basis of said positioning charge information contained in said aid information, a position-relevant-signal reception device being configured to receive the position-relevant signals on the basis of said aid information, a positioning-basis-information generation device being configured to generate positioning basis information on the basis of said position-relevant signals, a terminal-located-result-information generation device being configured to determine said current position on the basis of said positioning basis information to generate terminal-located position information and signal reception time information indicating signal reception times of said position-relevant signals, a positioning-basis-information correction device being configured to correct the positioning basis information on the basis of the signal reception time information to generate corrected positioning basis information, a corrected-positioning-basis-information transmission device being configured to transmit said corrected positioning basis information to said information providing apparatus on the basis of a judged result of said information-providing-apparatus-sort judgment device, a information-providing-apparatus-located-position-information acquisition device being configured to acquire information-providing-apparatus-located position information indicating a result of location based on said corrected positioning basis information indicated by said information providing apparatus, and a located-position-information output device being configured to output said terminal-located position information or said information-providing-apparatus-located position information on the basis of a judged result of said information-providing-apparatus-sort judgment device.
