This invention concerns mobile communication positioning systems (MCPS). These types of systems include cellular telephone systems, paging systems, personal communication systems and low earth orbit telephone satellite systems. In particular, the invention addresses systems which include a facility to make timing measurements between their base stations and a mobile, in order to indicate the distance of the mobile from at least one of the base stations. The distance indications in these systems will often be processed to produce an ambiguous indication of the position of the mobile and the invention concerns the resolution of this ambiguity using one or more techniques relying on alternative sources of information that are described.
