Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method and apparatus for determining time in a satellite positioning system.

SOLUTION: In one embodiment a reference time is used to determine other navigational information. Such navigational information includes for example the location/position of a satellite positioning system (SPS) receiver. In one embodiment a relative velocity between the SPS receiver and a set of one or more satellites is used to determine an offset between time as indicated by the SPS receiver and the reference time. According to another embodiment of the invention an error statistic is used to determine the reference time. According to yet another embodiment of the invention two records respectively representing at least the positions of the satellites are compared to determine time. In one implementation the SPS receiver is mobile and operates in conjunction with a base station so as to determine time and/or other navigational information according to one or a combination of the methods.
