Abstract
The present invention relates to a method for selecting satellites (SV -SV ) to be used for positioning in a positioning system. The positioning system comprises information on the orbits of the satellites (SV -SV ). In the method, at least one satellite (SV -SV ) to be searched for is selected at a time, and a searching step is performed to find out if the signal transmitted by at least one selected satellite (SV -SV ) can be received. In the method, at least a first searching step and at least one continued selection step are performed, wherein in the continued selection step, at least one satellite (SV -SV ) is selected at least partly on the basis of the findings of the previous searching step. The selection step is followed by the satellite searching step.
