Abstract
Description
Staffelbauweise einer feststehenden Satellitenantenne.Relay construction of a fixed satellite antenna.
Die Erfindung betrifft die Anordnung von Satelliten- Strahlenreflektoren. Durch hintereinander angeordnete Strahlenreflektoren nach Anspruch 1 ist es möglich, mit einer feststehenden Antennenanlage Hörfunk- und Fernseh programme mehrerer, auf der geostationären Umlaufbahn bis zu einem gewissen Abstand nebeneinander liegender Satelliten zu empfangen, ohne dabei die Ausrichtung der Antennenanlage bzw. einzelner Teile davon verändern zu müssen. Voraussetzung dafür ist die für die jeweiligen Satelliten erforderliche Mindestgröße der parabolischen Reflektoren, wobei hinsichtlich der Größe des jeweils hinteren Reflektors die durch die vorgelagerten Reflek toren abgeschirmte Fläche zu berücksichtigen ist. Weitere Voraussetzung ist eine für einen teilweisen seitlichen Strahleneinfall geeignete Empfangselektronik.The invention relates to the arrangement of satellite Radiation reflectors. By arranged in a row Radiation reflectors according to claim 1, it is possible with a fixed antenna system radio and television programs of several, on the geostationary orbit to at a certain distance from each other To receive satellites without changing the orientation of the Antenna system or individual parts of it change have to. The prerequisite for this is that for the respective Satellite required minimum parabolic size Reflectors, with regard to the size of each rear reflector by the upstream reflect shielded area must be taken into account. Further One requirement is for a partial lateral Radiation incidence suitable receiving electronics.
Es ist bekannt, daß mit feststehenden Parabolantennen, welche mit nur einer Empfangselektronik und nicht mit Nebenreflektoren ausgestattet sind, nur der Empfang von Programmen eines Satelliten möglich ist. Für den Empfang von Programmen anderer Satelliten ist die Ausrichtung der gesamten Antennenanlage oder einzelner Teile davon zu verändern.It is known that with fixed parabolic antennas, which with only one receiving electronics and not with Auxiliary reflectors are only equipped to receive Programs of a satellite is possible. For the reception of programs from other satellites is the orientation of the entire antenna system or individual parts thereof change.
Das Drehen und Schwenken von bisher üblichen Antennenan lagen erfordert einen erheblichen technischen Aufwand mit entsprechend hohem Verschleiß. Des weiteren werden durch den Bewegungsantrieb Energie verbraucht und Geräusche verur sacht.The turning and swiveling of previously used antennas layers requires considerable technical effort correspondingly high wear. Furthermore, the Motion drive consumes energy and makes noise gently.
Der Erfindung liegt die Aufgabe zugrunde, mit einer fest stehenden, nicht dreh- und schwenkbaren Antennenanlage den Empfang von Hörfunk- und Fernsehprogrammen mehrerer Satelliten unterschiedlicher Position zu ermöglichen. The invention has for its object with a fixed standing, not rotatable and swiveling antenna system Reception of radio and television programs from several To enable satellites of different positions.
Diese Aufgabe wird erfinderisch dadurch gelöst, daß mehrere parabolische Strahlenreflektoren hintereinander angeordnet werden. Die einzelnen Reflektoren werden so gestaltet und auf den jeweiligen Satelliten ausgerichtet, daß die Brennpunkte der von den einzelnen Reflektoren ausgehenden Strahlenkegel verschiedener Satelliten auf einem gemeinsamen Punkt zusammentreffen. Im Bereich dieses Punktes ist die Empfangselektronik anzuordnen. Die Befes tigung des vorgelagerten Reflektors bzw. der vorgelagerten Reflektoren sollte so konstruiert werden, daß auch eine nachträgliche Veränderung der Position der Reflektoren problemlos möglich ist, um Programme von Satelliten anderer Lage empfangen zu können.This object is achieved according to the invention in that several parabolic radiation reflectors in a row to be ordered. The individual reflectors are like this designed and aligned to the respective satellite, that the focal points of that from the individual reflectors outgoing beam cone of different satellites meet at a common point. In the area of this The reception electronics must be arranged at this point. The Befes adjustment of the upstream reflector or upstream Reflectors should be designed so that one subsequent change in the position of the reflectors is easily possible to programs from satellites to be able to receive in a different location.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß statt mit einer technisch aufwen digen dreh- und schwenkbaren Satellitenantennenanlage bereits mit einer feststehenden Antennenanlage der Empfang von Hörfunk- und Fernsehprogrammen mehrerer Satelliten möglich ist. Damit entfällt die gesamte Antriebstechnik sowie der entsprechende Energieverbrauch. Ferner entfallen die Antriebsgeräusche sowie der Verschleiß beweglicher Teile.The advantages achieved with the invention exist especially in that instead of using a technically complex rotating and swiveling satellite antenna system reception with a fixed antenna system of radio and television programs from several satellites is possible. This eliminates the entire drive technology as well as the corresponding energy consumption. Furthermore omitted the drive noise and wear more mobile Parts.
Die Systemskizzen stellen beispielhaft die Funktionsweise der Staffelanordnung einer Antennenanlage in Offsetbauweise dar, womit z. Zt. die Hörfunk- und Fernsehausstrahlungen der Satelliten "Kopernikus" und "ASTRA" empfangen werden können. Der Vertikalschnitt - Fig. 1 - zeigt die Anordnung der Antennenbauteile und den Verlauf der Strahlen von den Satelliten über die jeweiligen Parabolreflektoren ((1) = Kopernikus-Reflektor) ((2) = ASTRA-Reflektor) zur gemeinsamen Empfangselek tronik (3). Die Fig. 2 zeigt die Antennenbauteile und den Strahlenverlauf im Vertikalschnitt.The system sketches represent an example of the functioning of the staggered arrangement of an antenna system in offset construction. The radio and television broadcasts from the satellites "Kopernikus" and "ASTRA" can currently be received. The vertical section - Fig. 1 - shows the arrangement of the antenna components and the course of the rays from the satellites on the respective parabolic reflectors (( 1 ) = Copernicus reflector) (( 2 ) = ASTRA reflector) for common receive electronics ( 3 ). Fig. 2 shows the antenna elements and the beam path in the vertical section.
