Abstract
A method in a satellite positioning system receiver, including acquiring (210) a set of satellite positioning system satellites, determining (220) satellite subset time based on over-determined position solutions for at least two different subsets of the satellites acquired, determining (230) satellite time from at least two satellite subset times, computing (250) a position solution based on the satellite time or a refined (240) satellite time.
Claims9
A satellite positioning system receiver, comprising:
- a satellite signal receiver;
- a controller coupled to the satellite signal receiver,
- the controller configured to determine time from at least two satellite subset times,
- the satellite subset times obtained based on over-determined position solutions for at least two different subsets of satellites acquired by the satellite signal receiver.
