A method for searching satellites is disclosed. In the method of the present invention, the satellites are selected to consist of a group, and searching is conducted in this group. The group size is predetermined for each stage so as to be the most appropriate for various searching conditions. The member number of the group (i.e. group size) and the members of the group are updated as the searching results are continually obtained. The updates are done according to scanning times of the group, satellite hit number, searching time for the group and satellite priorities and the like, for example. The group size can be reduced or expanded. By using the method, satellites required to fix a position can be rapidly found.
