ABSTRACT:
A position determining system takes the form of a cellular radio system including at least one base station having a base station satellite receiver (6) and a mobile unit including a cellular mobile station (50) coupled to a local satellite receiver (58). The base station transmits base station satellite data via a cellular radio link to the mobile unit, the data including data representing a carrier phase measurement derived from a satellite signal (70) received by the base station satellite receiver (6). The mobile unit determines its position relative to the base station using local satellite data received by the local satellite receiver (58) and corrects errors in this position determination using base station satellite data. The relative positions of the base stations are determined automatically with reference to an external positional reference which may be a satellite-based position determining system.
