Zusammenfassung:The invention relates to a device (10; 100) for receiving linearly polarised satellite signals, comprising at least one first and one second decoupling probe (14; 16), which are oriented at an angle to one another and project into a waveguide (12), and each provide a linearly polarised input signal, and comprising a signal processing unit (13) for processing the two input signals. In order to further develop the device (10; 100) in such a way that it permits a noise-immune electronic correction of a polarisation squint angle, according to the invention: the signal processing unit (13) has a first combination element (22), which generates opposing elliptically polarised high-frequency signals from the linearly polarised input signals; and the signal processing unit (13) has controllable signal conversion arrangements (32, 38), which convert the elliptically polarised high-frequency signals into elliptically polarised intermediate-frequency signals, wherein the intermediate-frequency signals have a predefinable phase difference in relation to one another; and the signal processing unit (13) has a second combination element (66), with the aid of which the elliptically polarised intermediate-frequency signals can be combined to form a linearly polarised output signal.
