Abstract

A method of determining the location of a mobile receiver is provided. The method works within a radio system in one or more dimensions, the radio system includes a network of transmitters the positions of which are known. The method comprises the steps of: compiling a list of the signals detected by the receiver; sending said list to a calculation device; constructing a position function which relates to the probability that the receiver is at a given location, which position function has components corresponding to each member of the list, each component including a predetermined probability function that depends on mobile receiver position; and evaluating said position function to determine a position that corresponds to the highest probability of location, and defining that position to be the location of the mobile receiver.
