Abstract
The invention relates to a method for increasing the accuracy of a measurement of a radio-based locating system comprising a mobile station and at least one fixed station, wherein the movement of a mobile station from an initial position is detected by way of measuring data of an absolute sensor system and a relative sensor system, a virtual antenna is embodied in the form of synthetic aperture by way of measuring data and the mobile station is focused on the fixed station and/or vice versa by using the synthetic aperture.

21. A method for increasing measurement precision of a radio-based positioning 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, and focusing either;
a) the mobile station on the stationary station and;
b) the stationary station on the mobile station, the focusing utilizing the synthetic aperture. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
