ABSTRACT:
A method for searching satellites in a cold start state. The method of the present invention, a first satellite, which is predetermined or randomly selected, is searched. Then, a second satellite to be searched is selected according to the searching result (hit or missed) for the first satellite and respective interrelationships between the first satellite and the other satellites. In practice, an initial weight factor table is provided. Depending on the searching result, the initial weight factor table is updated according to the interrelationships between the satellites during searching. By using the method of the present invention, the time-to-first-fix (TTFF) can be reduced to a shorter period of time so as to provide a rapid cold start satellite positioning.
