Title: POSITIONING DEVICE, POSITIONING SYSTEM, POSITIONING METHOD, AND POSITIONING PROGRAM
Abstract:
[Problem] To rapidly determine integral bias. [Solution] This positioning device comprises a floating solution computation unit 61 and an integral bias determination unit 62. The floating solution computation unit 61 uses the carrier wave phase contrast between a carrier wave phase obtained by one or more antennas of a first station and a carrier wave phase obtained by each of a plurality of antennas of a second station to compute a floating solution for the specific position of the second station without using the attitude angle of the second station. The integral bias determination unit 62 uses the floating solution for the specific position and the attitude angle of the second station to determine the integral bias of the carrier wave phase contrast.
