PROBLEM TO BE SOLVED: To enhance the positioning accuracy of a positioning device while keeping its configuration inexpensive.SOLUTION: A satellite positioning system comprises a satellite positioning device and a positioning correction information supplying device that supplies information regarding positioning satellites to the satellite positioning device. A correction information supplying device generates, regarding at least one positioning satellite, satellite information including information indicating the appropriateness regarding the use of satellite signals from the positioning satellite for positioning satellite, and transmits it to the satellite positioning device. The satellite positioning device decides, on the basis of the satellite information received from the positioning correction information supplying device, on satellite signals to be used for positioning, and figures out positional information on the basis of the satellite signals decided upon.SELECTED DRAWING: Figure 1
【課題】測位装置を安価な構成としつつ、その測位精度を向上させる。【解決手段】衛星測位システムは、衛星測位装置と、該衛星測位装置に対して測位衛星に関する情報を提供する測位補正情報提供装置からなる。補正情報提供装置は、少なくとも一つの測位衛星について、当該測位衛星からの衛星信号を測位に使用することに関する適切さを示す情報を含む衛星情報を生成して衛星測位装置へ送信する。衛星測位装置は、測位補正情報提供装置から受信した衛星情報に基づいて測位に使用する衛星信号に決定し、決定された衛星信号に基づいて位置情報を算出する。【選択図】図1
