Abstract
A satellite receiver is switchable between an operating mode wherein the receiver is capable of generating an output signal using received signals from one or a plurality of satellites, aid another operating mode wherein the receiver generates an output signal using signals received from only one satellite. The former operating mode is useful when the receiver is operating in a mobile environment. The latter operating mode is useful when the receiver is operating in a fixed environment. The receiver is configured to detect the mode in which it is operating. The receiver comprises at least two recevier arms for processing a broadcast signal from a selected one of two satellites. The receiver disables one of the arms when the receiver is stationary.
