Abstract
An acquisition apparatus for acquiring the positional information indicating the position of a position detecting device which, in one embodiment, detects position based on a GPS (Global Positioning System). The position detecting device measures the device distance to each of a plurality of satellites and calculates the device position based on the device distance and the position of each of the plurality of satellites. The acquisition apparatus comprises a receiving part for receiving the device distance and the device position from the position detecting device, and a verification position calculating part for calculating the verification position that is the position to be calculated by the position detecting device, based on the received device distance and the position of each of the plurality of satellites at the time of measuring the device distance. The apparatus further includes a validity judgment part for judging that the device position detected by the position detecting device is valid, on condition that the device position is coincident with the verification position.
