Global positioning system receiver and satellite clock correcting method thereof
First Claim
1. A global positioning system receiver comprising:
- a satellite signal receiving part constructed and arranged to extract navigation data from a satellite signal received from at least one satellite;
a decoder constructed and arranged to decode the navigation data;
a satellite location determining part constructed and arranged to determine a location of the at least one satellite according to the decoded navigation data; and
a satellite clock correcting part constructed and arranged to calculate a velocity of the at least one satellite and to correct a satellite clock based on at least one of the calculated satellite velocity and the location of the at least one satellite.
