Abstract
A satellite search method and a receiver implementing such a method are disclosed. In the present invention, a predetermined range is sampled into multiple possible positions or space-time points, each of which is defined by a specific position and a time sample. The possible positions or points are sieved according to a search result of a satellite selected from candidate satellites each time. By repeatedly doing so, the finally remaining position will approach a user's position, and accordingly the candidate satellites converge to the most possible ones as to facilitate satellite search.
