摘要

PROBLEM TO BE SOLVED: To solve the problem that an amount of data used when acquiring position data on a terminal is not sufficiently reduced.SOLUTION: A positioning device comprises: a satellite signal reception part for receiving satellite signals of one or more satellites; an own terminal information group acquisition part for acquiring an own terminal information group on an own terminal, including an own terminal pseudo distance which is a pseudo distance between the own terminal and each satellite by using the satellite signal for each of one or more satellites; an own terminal information group output part for outputting a part or all of information of the own terminal information group; a position acquisition part for acquiring position data on the own terminal by using the own terminal pseudo distance; and a position output part for outputting the position data acquired by the position acquisition part. The positioning device with the own terminal information group output part which in certain cases may output only information which is partial information of the own terminal information group used for acquiring the position information, including unpredictable information among the own terminal information group allows an amount of data used to be sufficiently reduced.
