Abstract  Abstract

A method and apparatus for determining a reference time associated with a satellite positioning system. In turn the reference time in one embodiment may be used to determine other navigational information. Such navigational information may include for example the location/position of a satellite positioning system (SPS) receiver. In one embodiment a relative velocity between an 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 each representing at least a portion of a satellite message are compared to determine time. In one implementation the SPS receiver is mobile and operates in conjunction with a basestation to determine time and/or other navigational information according to one or a combination of the methods described.
