A MODEL BASED POSITIONING SYSTEM

摘要

The present invention relates to a model based positioning system (10); 90 that comprises a positioning device (11); 31 having at least one transmitter configured to be in a tracking environment, e.g. inserted into a body (1), a receiver (13) having a plurality of receiver elements (14) arranged outside the tracking environment, a control unit (18); 93 configured to measure amplitude and/ or phase information of a signal transmitted from the at least one transmitter and received at each receiving element, and a memory unit M; (15) for storing a model for each receiving element. The control unit is also configured to estimate the position P of the positioning device by comparing the model for each receiving element with the measured received signal for each receiving element.
