Abstract
A positioning satellite selection device that obtains a selection combination of positioning satellites used for positioning of a positioning target, and includes: a positioning data acquisition unit that acquires positioning data or navigation information, a range observation value, and an error correction value of this range observation value of a positioning satellite; a satellite position calculator that calculates a satellite position of the positioning satellite from the navigation information; a quality evaluation unit that evaluates quality of the positioning data; a shortest time designation unit that sets a shortest selection time during which the positioning satellite is selected to a larger value as poorer the quality; a plan creator that obtains the selection combination by selecting a positioning satellite conditioned on selecting for longer than the shortest selection time; and a plan storage that stores a plan of the selection combination of positioning satellites.
