C Mobile Empfangseinrichtung für Fernsehrundfunksatelliten mit automatischer Ausrichtung der Antenne. ) C Mobile reception device for television broadcasting satellites with automatic antenna alignment. )

1) Stand der Technik1) State of the art

Üblicherweise werden Antennen für Fernsehrundfunksatelliten manuell ausgerichtet. Als Hilfsmittel dienen lediglich ein Kompaß und ein Feldstärkeinstrument zur Messung der 1. Zwischenfrequenz nach dem LNC.Antennas for television broadcasting satellites are usually aligned manually. The only tools needed are a compass and a field strength instrument to measure the first intermediate frequency after the LNC.

2) Problem2) Issues

Nach jedem Standortwechsel der Empfangsanlage muß die Antenne erneut auf den Satelliten ausgerichtet werden. Durch die ausgeprägte Richtcharakteristik der Antenne ist die manuelle Ausrichtung sehr schwierig, zumal zwei Freiheitsgrade (Azimut und Elevation) einzustellen sind.Every time the receiving system is moved, the antenna must be aligned to the satellite again. Due to the antenna's pronounced directional characteristics, manual alignment is very difficult, especially since two degrees of freedom (azimuth and elevation) must be adjusted.

3) Erfindung3) Invention

Ausgehend vom Stand der Technik liegt der Erfindung die Aufgabe zugrunde eine Antenne vollautomatisch optimal auf einen Fernsehrundfunksatelliten auszurichten.Based on the state of the art, the invention is based on the task of optimally aligning an antenna fully automatically to a television broadcasting satellite.

4) Vorteilhafte Wirkungen der Erfindung4) Advantageous effects of the invention

Das Ausrichten der Antenne nach einem Standortwechsel der Empfangsanlage muß nicht mehr manuell durchgeführt werden. The antenna no longer needs to be aligned manually after the receiving system has been moved.

5) Darstellung der Erfindung5) Description of the invention

Die mobile Empfangseinrichtung besteht aus einem Satelliten empfänger, einer motorisch bewegbaren Antenneneinheit und ei nem Steuergerät. The mobile receiving device consists of a satellite receiver, a motor-driven antenna unit and a control unit.

Durch das Steuergerät wird die Antenne motorisch so bewegt, daß der für Fernsehrundfunksatelliten interessierende Bereich des Himmels systematisch abgetastet wird.The control unit moves the antenna in such a way that the area of the sky that is of interest to television broadcasting satellites is systematically scanned. Sobald der Satellit gefunden ist, wird die Antenne automatisch so ausgerichtet, daß der optimal mögliche Empfang gewährleistet ist.As soon as the satellite is found, the antenna is automatically aligned to ensure the best possible reception.
