Abstract
An apparatus for vector tracking a plurality of satellite signals received by a Global Navigation Satellite System (GNSS) receiver from a plurality of satellites and a method for use thereof. The apparatus comprises: a hypothesis determiner configured to determine a most likely velocity hypothesis from a plurality of velocity hypotheses based on a plurality of correlation values, and to transfer data related to the most likely velocity hypothesis to a navigation engine of the GNSS receiver for tracking the satellite signals, wherein the plurality of velocity hypotheses have been generated based on a navigation engine output indicative of a current and/or a previous extended velocity solution for the GNSS receiver; and wherein the plurality of correlation values have been determined by a plurality of correlators and represent correlations between a plurality of first signals each comprising an expected Doppler shift derived from one of the plurality of velocity hypotheses, and a plurality of second signals each comprising a true Doppler shift derived from one of the plurality of satellite signals.
