Abstract: This specification relates to estimation of a location of a mobile device using one or more locator devices. In a first aspect, this specification describes an apparatus comprising: means for receiving, from a set of locator devices at known locations, each locator device comprising an antenna array, bearing measurements indicative of one or more bearings from the antenna array of each of the plurality of locator devices to a mobile device; means for estimating a position of the mobile device using the known location of each locator device and the bearing measurements from each locator device; means for determining, for each of the bearing measurements, an error based on the bearing measurement and the estimated position of the mobile device; means for identifying one or more bearing measurements having an error in excess of a threshold; and means for re-estimating the position of the mobile device such that the contribution of the identified one or more bearing measurements to the re-estimated position is reduced.
