Abstract
An example method of determining a position of a mobile device includes, for each of a plurality of anchor points, receiving respective relative position information between the respective anchor point and the mobile device such that the received relative position information for the plurality of anchor points forms a set of position information, each relative position information including at least one of: a direction between the respective anchor point and the mobile device, a distance between the respective anchor point and the mobile device, or a direction and a distance between the respective anchor point and the mobile device. The method includes determining an estimated position of the mobile device based on the set of position information; defining a set of loci, each locus of the set of loci being based on one or more of the relative position information from the set of position information; determining, for each locus of the set of loci, a distance value between the estimated position of the mobile device and the respective locus; determining, for each locus of the set of loci, a weight factor as a function of the determined distance values; and determining a refined position of the mobile device based on the set of position information and the determined weight factors. A positioning engine for determining a position of a mobile device is disclosed as well.
