Abstract:
1. A method for increasing measurement precision of a radio-based position determination system comprising a mobile station and at least one stationary station, the method comprising: detecting a movement of the mobile station starting from an initial position, the detecting utilizing measurement data of an absolute sensor system and a relative sensor system; generating a virtual antenna in a form of a synthetic aperture utilizing the measurement data by relative coordinates to a reference point, and focusing either: a) the mobile station on the stationary station or; b) the stationary station on the mobile station, the focusing utilizing the synthetic aperture; wherein the absolute sensor system is generated from at least one secondary radar and at least one transponder; and wherein either: c) the mobile station is the secondary radar and the at least one stationary station is the transponder or; d) the mobile station is the transponder and the at least one stationary station is the secondary radar.
