Abstract  Abstract

(57) Abstract: A method and apparatus for determining a reference time for a satellite positioning system. In one embodiment, the reference time is used to determine other navigation information. Such navigation information includes, for example, the local / position of a satellite positioning system (SPS) receiver. In one embodiment, the relative speed between the SPS receiver and one or more groups of satellites is used to determine the offset between the time as indicated by the SPS receiver and the reference time. . For another embodiment of the invention, correction statistics are used to determine reference time. According to another embodiment of the invention, two records each representing at least the position of the satellite are compared to determine a time. In one implementation, the SPS receiver is mobile and operates to determine time and / or other navigation information relative to the base station by one or a combination of plowing methods.
