Abstract
The invention relates to a method for attenuating interferences in a positioning receiver, wherein a signal transmitted by the satellites of a positioning system is received, and the received signal is amplified. In the positioning receiver a noise level of the received signal is determined, the existence of interferences is established on the basis of changes of the determined noise level, and the amplification is controlled on the basis of the noise level of the signal received otherwise than during interference. The invention also relates to an electronic device, wherein the method is applied, as well as to a program, with which the method can be implemented in connection with the positioning receiver.
