Beschreibung
Zusammenfassung:	A satellite communication ground station configured for communicating over an inclined orbit geostationary satellite may include a tracking antenna having three fixed axis and one moving axis, a motor (150) for swinging the antenna along the moving axis, a controller (120) for controlling the motor, a receiver (130) configured to receive a signal arriving from the satellite via the tracking antenna and an estimator (140) configured to estimate reception quality of a signal received by the receiver. Furthermore, a method for tracking an inclined orbit geostationary satellite, the method comprising a learning step and a tracking step, wherein the learning step includes use of a filter for reducing alignment errors and reducing the amount of peaking required for aligning the antenna with the satellite and tracking its movement.
