METHOD AND APPARATUS FOR DETERMINING THE POSITION AND ORIENTATION OF A MOBILE TRANSMITTER

摘要

A method and an apparatus are proposed are proposed for determining the position and orientation of a mobile transmitter which has at least two linearly polarized antennas which are arranged at a predetermined angle with respect to one another. A plurality of receivers which can be synchronized with the mobile transmitter and the position of which is known, and which each have a circular-polarized antenna, in this case receive transmitted signals at a predetermined carrier frequency. According to the method, a field-theoretical model of the transmission path between the mobile transmitter and the receivers is created, which defines carrier-phase measured values, implements the field-theoretical model in a Kalman filter, and evaluates the received signals with respect to the carrier-phase measured values and/or propagation times. Finally, the position and orientation of the mobile transmitter are determined in the Kalman filter using the field-theoretical model and the carrier-phase measured values and/or propagation times determined from the received signals.
