To perform satellite positioning capable of securing requested positioning performance.SOLUTION: Electronic equipment 1 comprises a GPS unit 16, a GPS information acquisition unit 51, a sensor information acquisition unit 52, and a reception condition determination unit 54. The GSP unit 16 receives a radio wave from a positioning satellite. The GPS information acquisition unit 51 acquires ephemeris information by the GPS unit 16, and acquires satellite arrangement information of each of a plurality of positioning satellites which acquired the ephemeris information. The sensor information acquisition unit 52 acquires location condition information of a current place in which the electronic equipment 1 exists. The reception condition determination unit 54 identifies the number of positioning satellites which can be captured in the current place among the plurality of positioning satellites which has acquired the ephemeris information on the basis of the location condition information of the current place and the satellite arrangement information.SELECTED DRAWING: Figure 3
【課題】要求される測位性能が担保できる衛星測位を行うこと。【解決手段】電子機器1は、GPS部16と、GPS情報取得部51と、センサ情報取得部52と、受信条件判定部54と、を備える。GPS部16は、測位衛星からの電波を受信する。GPS情報取得部51は、GPS部16によりエフェメリス情報を取得し、当該エフェメリス情報を取得した複数の測位衛星それぞれの衛星配置情報を取得する。センサ情報取得部52は、当該電子機器1が存在する現在地の立地条件情報を取得する。受信条件判定部54は、現在地の立地条件情報と衛星配置情報とに基づいて、エフェメリス情報を取得した複数の測位衛星のうち、現在地において捕捉可能な測位衛星の数を特定する。【選択図】図3
