Description

Die Erfindung betrifft eine Empfangsantenne für Satelliten-Direktempfang, mit einer schwenkbaren Antennenkonstruktion mit einem Antennenreflektor, insbesondere parabolischer Form.The invention relates to a receiving antenna for direct satellite reception, with a pivotable antenna construction with an antenna reflector, in particular parabolic shape.

Zur unmittelbaren, direkten Versorgung von Heimempfängern mit Fernseh- und Eörfunkprogrammen können sogenannte Fernsehrundfunk-Satelliten oder Fernseh-Direktsatelliten herangezogen werden, die von einer Bodensendestation angestrahlt werden und das empfangene Programm direkt an die Fernsehteilnehmer verteilen. Diese Satelliten werden in eine bestimmte äquatoriale Erdumlaufbahn gebracht und bewegen sich synchron zur Erdumdrehung. Ein Fernsehrundfunk-Satellit kommt dadurch in einer "festen", sogenannten geostationären Position scheinbar zur Ruhe, d.h. er steht bezogen auf einen Punkt der Erdoberfläche nahezu still. Ein in Bezug auf die Erde stationärer Satellit erlaubt die Verwendung fest ausgerichteter und scharf bündelnder Antennen auf der Empfangsseite, die nicht nachgeführt zu werden brauchen.So-called television broadcasting satellites or direct television satellites can be used for the direct, direct supply of home receivers with television and radio broadcasting programs, which are illuminated by a ground transmitter and distribute the received program directly to the television subscribers. These satellites are placed in a certain equatorial orbit and move synchronously with the Earth's revolution. A television broadcasting satellite thus appears to come to rest in a "fixed", so-called geostationary position, i.e. it stands almost still in relation to a point on the earth's surface. A satellite that is stationary with respect to the earth allows the use of fixedly aligned and sharply focused antennas on the receiving side, which do not need to be tracked.

Beim Satelliten-Direktempfang müssen die Empfangsantennen auf den im,0rbit positionierten Satelliten, dessen Position durch seine Elevation und seinen Azimut für die verschiedenen Empfangsorte gekennzeichnet ist, ausgerichtet werden. Es besteht daher die Aufgabe, die Empfangsantenne nach den örtlichen Positionsdaten des Satelliten auszurichten. Erst dann kann die Feinjustage anhand der empfangenen elektrischen Signale (maximale Empfangsspannung) durchgeführt werden. Eine ausschließliche Justage anhand der empfangenen Signale käme wegen der Bündelungsschärfe der Antennen der Suche nach der Stecknadel im Heuhaufen gleich.In the case of direct satellite reception, the receiving antennas must be aligned with the satellite positioned in the 0rbit, the position of which is characterized by its elevation and azimuth for the various reception locations. There is therefore the task of aligning the receiving antenna according to the local position data of the satellite. Only then can the fine adjustment be carried out on the basis of the received electrical signals (maximum reception voltage). An exclusive Adjustment based on the received signals would be the same as looking for the pin in the haystack due to the bundling sharpness of the antennas.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Lösung anzuzeigen, die es dem Monteur einer für den Hausgebrauch vorgesehenen Empfangsantenne für Satelliten-Direktempfang auf einfache Weise ermöglicht, die Position der Empfangsantenne grob auf einen Direktsatelliten auszurichten.The invention is based on the object of indicating a solution which enables the installer of a reception antenna for direct satellite reception intended for domestic use in a simple manner to roughly align the position of the reception antenna with a direct satellite.

Diese Aufgabe wird bei einer Empfangsantenne der eingangs genannten Art gemäß der Erfindung dadurch gelöst, daß die schwenkbare Antennenkonstruktion selbst mit einer in festem Bezug zur elektrischen Achse der Antenne stehenden Referenzmarkierung versehen ist.This object is achieved in a receiving antenna of the type mentioned at the outset according to the invention in that the pivotable antenna construction itself is provided with a reference mark which is fixedly related to the electrical axis of the antenna.

Bei einer erfindungsgemäßen Empfangsantenne ist somit die elektrische Achse und damit die Hauptrichtung der Empfangskeule leicht erkennbar gekennzeichnet, so daß dem Monteur der Antenne die Grobausrichtung der Antenne auf den Direktsatelliten ohne Anwendungirgendwelcher langwieriger, umständlicher Peil- oder Meßverfahren ermöglicht wird. Die Grobausrichtung der Antenne ist daher dem Monteur auch bei einem schwierigen Standort, z.B. auf einem Hausdach, in einfacher Weise möglich.In the case of a receiving antenna according to the invention, the electrical axis and thus the main direction of the receiving lobe are thus identified in a manner that is easily recognizable, so that the antenna fitter can carry out the rough alignment of the antenna on the direct satellites without using any lengthy, cumbersome direction finding or measuring methods. The coarse alignment of the antenna is therefore the installer even in a difficult location, e.g. on a house roof, easily possible.

Bei einer erfindungsgemäßen Empfangsantenne wird der feste Bezug zwischen der Referenzmarkierung und der elektrischen Achse der Antenne in vorteilhafter Weise mittels eines Peilverfahrens bei der Herstellung und elektrischen Prüfung der Antenne geschaffen. Damit erhält der Monteur der Antenne diese bereits werksseitig mit der Kennzeichnung der elektrischen Achse versehen zur Montage.In the case of a receiving antenna according to the invention, the fixed reference between the reference marking and the electrical axis of the antenna is advantageously created by means of a direction finding process in the manufacture and electrical testing of the antenna. This gives the installer of the antenna the factory-provided identification of the electrical axis for mounting.

Zweckmäßigerweise ist bei einer erfindungsgemäßen Empfangsantenne die Referenzmarkierung an dem Antennenreflektor vorgesehen.In a receiving antenna according to the invention, the reference marking is expediently provided on the antenna reflector.

Die Referenzmarkierung kann in einfacher Weise dadurch gebildet werden, daß sie mit einer zur elektrischen Achse der Antenne parallel gerichteten und in Richtung der elektrischen Achse verlaufenden Kante ausgebildet ist. Eine derartige Kante ist auch hinsichtlich einer eventuellen Ankopplung eines Ausrichtgerätes zur Einstellung der Antenne in Azimut und Elevation von Vorteil.The reference marking can be formed in a simple manner in that it is formed with an edge which is parallel to the electrical axis of the antenna and extends in the direction of the electrical axis. Such an edge is also advantageous with regard to a possible coupling of an alignment device for setting the antenna in azimuth and elevation.

Bei einem vorteilhaften Ausführungsbeispiel einer erfindungsgemäßen Empfangsantenne weist die Referenzmarkierung zwei miteinander verbundene Teile auf, von denen das eine Teil um eine erste Achse schwenkbar an der Antennenkonstruktion und das zweite Teil um eine zur ersten Achse senkrechte Achse schwenkbar-an dem ersten Teil gelagert ist. Auf diese Weise läßt sich durch das zweite Teil eine einstellbare Anlagefläche für ein Ausrichtgerät bilden. Eine besonders einfache Ausführungsform einer derartigen Referenzmarkierung ergibt sich, wenn die beiden Teile aus ebenen, aneinanderliegenden Platten bestehen, die an zu.einander parallel benachbarten Längsseiten jeweils rechtwinklig abgebogene Leisten aufweisen. Dabei ist es zweckmäßig, wenn die Leiste der zweiten Platte die Referenzmarkierung bildet und gleichzeitig zur Aufnahme einer Stellschraube für die Vertikalverschwenkung der zweiten Platte dient.In an advantageous exemplary embodiment of a receiving antenna according to the invention, the reference marking has two interconnected parts, one of which is mounted on the antenna structure and the second part is pivotable on the first part and is pivotable about an axis perpendicular to the first axis. In this way, an adjustable contact surface for an alignment device can be formed by the second part. A particularly simple embodiment of such a reference marking is obtained if the two parts consist of flat, adjacent plates which each have strips bent at right angles on longitudinal sides which are adjacent to one another. It is expedient if the bar of the second plate forms the reference mark and at the same time serves to receive an adjusting screw for the vertical pivoting of the second plate.

Bei der Installation einer Empfangsantenne für Satelliten-Direktempfang durch den Monteur muß die Antenne nicht nur grob, sondern auch in Elevation und Azimut auf die Orbitposition des gewünschten Satellitensenders eingestellt werden. Einer Weiterbildung der Erfindung liegt daher die Aufgabe zugrunde, eine Lösung aufzuzeigen, mit welcher der Monteur einer für den Hausgebrauch vorgesehenen Empfangsantenne für Satelliten-Direktempfang auf einfache Weise die Position der Empfangsantenne möglichst genau auf einen Direktsatelliten auszurichten im Stande ist.When installing a receiving antenna for direct satellite reception by the installer, the antenna must not only be set roughly, but also in elevation and azimuth to the orbit position of the desired satellite transmitter. A further development of the invention is therefore based on the object of demonstrating a solution with which the fitter of a reception antenna for satellite di intended for domestic use direct reception is able to align the position of the receiving antenna as precisely as possible with a direct satellite.

Diese Aufgabe wird bei einer Weiterbildung der erfindungsgemäßen Empfangsantenne dadurch gelöst, daß eine Einrichtung zur Einstellung der Antenne in Elevation und Azimut vorgesehen ist und daß diese Einrichtung mit einer Anlagekante oder -fläche versehen ist, welche mit der Referenzmarkierung koppelbar ist.This object is achieved in a further development of the receiving antenna according to the invention characterized in that a device for adjusting the antenna in elevation and azimuth is provided, and that this device is provided with a contact edge or surface, which with the g Referenzmarkierun be coupled.

Bei einer derartigen Empfangsantenne kann der Monteur mit Hilfe der Einstelleinrichtung die Position der Antenne genau auf den Satelliten ausrichten. Dabei ist dem Monteur auch die Ausrichtung der Antenne auf den Direktsatelliten in Azimut und Elevation ohne Anwendung irgendwelcher aufwendiger, langwieriger Meßverfahren ermöglicht. Die Antenne kann deshalb auch bei einem schwierigen Standort genau ausgerichtet werden. Diese Einstelleinrichtung kann ständig oder vorüber- gehend mit der Referenzmarkierung gekoppelt werden und ist dann ohne weiteres lagerichtig in Bezug auf die elektrische Achse der Antenne an der Antennenkonstruktion angekoppelt.With such a receiving antenna, the fitter can use the setting device to align the position of the antenna precisely with the satellite. The fitter is also able to align the antenna on the direct satellites in azimuth and elevation without using any complex, lengthy measuring methods. The antenna can therefore be precisely aligned even in a difficult location. These adjustment means may permanently or temporarily - be continuously coupled to the reference marking and is then readily correct position coupled with respect to the electrical axis of the antenna on the antenna structure.

Bei einem besonders vorteilhaften Ausführungsbeispiel einer erfindungsgemäßen Empfangsantenne mit Einstelleinrichtung ist diese in zwei zueinander senkrecht stehenden Ebenen mit jeweils einer Winkelgrad-Skala ausgebildet, wobei die Winkelgrad-Skala für die Elevationseinstellung in festem Bezug zur Waagerechten und die Winkelgrad-Skala für die Azimuteinstellung in festem Bezug zur Nord-Süd-Richtung steht. Bei einer derartigen Ausführungsform einer erfindungsgemäßen Empfangsantenne ist es ferner vorteilhaft, wenn die Einstelleinrichtung in derjenigen Ebene, in welcher die Winkelgrad-Skala für die Azimuteinstellung vorgesehen ist, mit einem mit dieser Skala in Bezug stehenden Kompaß und einer Vorrichtung zur Einstellung der Waagerechten versehen ist. Dabei besteht diese Vorrichtung zweckmäßigerweise aus einer Libelle. Eine derartige Einstelleinrichtung ist vom Installateur einfach zu bedienen und arbeitet hinreichend genau.In a particularly advantageous embodiment of a receiving antenna according to the invention with an adjusting device, it is formed in two mutually perpendicular planes, each with an angular degree scale, the angular degree scale for the elevation adjustment in a fixed reference to the horizontal and the angular degree scale for the azimuth adjustment in a fixed reference to the north-south direction. In such an embodiment of a receiving antenna according to the invention, it is also advantageous if the setting device in the plane in which the angular degree scale is provided for the azimuth adjustment is provided with a this scale related compass and a device for adjusting the horizontal is provided. This device expediently consists of a dragonfly. Such a setting device is easy to use by the installer and works with sufficient accuracy.

Die Anlagekante der Einstelleinrichtung wird bei einer erfindungsgemäßen Empfangsantenne mittels der Winkelgrad-Skala für die Elevationseinstellung in festen Bezug zur Waagerechten (Libelle) und mittels der Winkelgrad-Skala für die Azimuteinstellung in festen Bezug zur Nord-Süd-Richtung (Kompaßnadel) gebracht. Die Einstellung der Winkelgrad-Skala wird zweckmäßig vor der Montage der Antenne unter Berücksichtigung der für den Empfangsort gültigen Daten für Elevation und Azimut vorgenommen. Es ist somit eine große Erleichterung, wenn die Elevation der Antenne recht genau und ihr Azimut auf wenige Winkelgrade voreingestellt werden können. Der oftmals in exponierter Lage arbeitende Installateur muß dann beim Ausrichten der Antenne lediglich die Libelle in die Mittellage und die Kompaßnadel in die Nord-Süd-Richtung bringen. Diese Verrichtungen können mit einer Hand durchgeführt werden. Das endgültige Auffinden der Satellitenposition wird anschließend durch Auswertung der aufgenommenen elektrischen Signale durch kontinuierliches Verändern des Azimut innerhalb weniger Winkelgrade erreicht. Letztlich schließt sich die Feinjustage anhand der aufgenommenen elektrischen Signale an.In a receiving antenna according to the invention, the contact edge of the setting device is brought into fixed relation to the horizontal (dragonfly) by means of the angular degree scale for the elevation setting and in fixed relation to the north-south direction (compass needle) by means of the angular degree scale for the azimuth setting. The angle degree scale is expediently set before the antenna is installed, taking into account the data for elevation and azimuth valid for the receiving location. It is therefore a great relief if the elevation of the antenna can be set very precisely and its azimuth can be preset to a few angular degrees. The installer, who often works in an exposed position, then only has to bring the level to the middle position and the compass needle in the north-south direction when aligning the antenna. These operations can be carried out with one hand. The final finding of the satellite position is then achieved by evaluating the recorded electrical signals by continuously changing the azimuth within a few angular degrees. Ultimately, the fine adjustment follows on the basis of the recorded electrical signals.

Bei einer mit einem Kompaß ausgebildeten Einrichtung können eventuelle Mißweisungen der Kompaßnadel, z.B. infolge in der Nähe befindlicher Eisenteile der Anten- 'ne, vor der Inbetriebnahme der Einrichtung eingeeicht werden.In one formed with a compass means any misdirections of the compass needle, for example, can ne as a result of nearby iron parts of the antennas', of the device are eingeeicht before use.

Ein vorteilhaftes Ausführungsbeispiel einer erfindungsgemäßen Empfangsantenne zum Direktempfang der von einem Fernsehrundfunksatelliten ausgesandten Signale ist im folgenden anhand einer Zeichnung näher beschrieben.An advantageous embodiment of a receiving antenna according to the invention for direct reception of the signals transmitted by a television broadcasting satellite is described in more detail below with reference to a drawing.

An der oberen Längsseite der Platte 3 ist diese mit einer zur Plattenebene rechtwinklig abgebogenen Leiste 8 versehen, welche im Bereich des der Schwenkachse 5 abgewandten Endes mit einem sich in Plattenlängsrichtung erstreckenden Langloch 9 für eine weitere Stellschraube 10 zur Vertikalschwenkung der zweiten Platte 4 ausgebildet ist. Diese ebenfalls mit einer Schraubenfeder versehene Stellschraube 10 ist in eine zur Leiste der hinteren Platte 3 parallele Leiste 11 der vorderen Platte 4 eingeschraubt, wobei die Leiste 11 an einer zur oberen Längsseite der Platte 3 parallelen, benachbarten Längsseite der Platte 4 rechtwinklig zur Plattenfläche abgebogen ist. Im Bereich der der Stellschraube 10 abgewandten Ecke nahe der Schwenkachse 5 der hinteren Plat- . te 3 ist die vordere Platte 4-mittels eines Bolzens 12 derart mit der hinterenPlatte 3 fest verbunden, daß die Platte 4 um die durch den Bolzen gebildete, zur Schwenkachse 5 senkrechte Drehachse 12 gegen die Platte 3 verschwenkt werden kann. Um diese mittels der Stellschraube 10 durchführbare Verschwenkung zu ermöglichen, ist die vordere Platte 4 an der der Drehachse 12 diametral gegenüberliegenden Ecke noch in der dargestellten Weise mit einem Langloch 13 und einer Führungs- und Arretierungsschraube 14 ausgebildet. Bei der in der Fig. 2 dargestellten Plattenanordnung bildet die Leiste 11 der vorderen Platte 4 die Kante, die parallel zur elektrischen Achse A1 der Antenne und in Richtung dieser Achse verläuft. Die Leiste 11 stellt somit die Referenzmarkierung dar. Diese ist mit.der Platte 4 in geeigneter Weise auch mit einer einstellbaren Anlagefläche ausgebildet, an welcher ein Ausrichtgerät zur Einstellung der Antenne in Azimut und Elevation aufgenommen und befestigt werden kann. Die Montage der Plattenanordnung an dem Antennenreflektor 1 und die Lage der Platte 3 zum Antennenreflektor sowie die Position der Platten 3 und 4 untereinander wird mittels eines Peilverfahrens bei der Herstellung und der elektrischen Prüfung der Antenne, also vor deren Montage vorgenommen.1 has a pivotable antenna construction with a parabolic antenna reflector 1, which is pivotable in a manner not shown about two mutually perpendicular axes in azimuth and elevation. To roughly align the antenna to the satellite position, the antenna reflector 1 of the pivotable antenna construction is formed on its outer surface, here in the region of its edge, with a reference marking 2, which is in fixed relation to the electrical axis A1 of the antenna. This reference marking 2 is designed as an edge 11 which is directed parallel to the electrical axis A1 and runs in the direction of the electrical axis and which is provided on an arrangement consisting of two interconnected parts 3 and 4. The detailed structure of this arrangement is shown in FIG. 2. The two interconnected parts 3 and 4 consist of two flat, rectangular plates of different sizes, the rear plate 3 being somewhat larger than the front plate 4 lying against it Plate 3 is formed on one side with a pivot axis / and, as can be seen in FIG. 1, is thus mounted on the antenna reflector 1 in such a way that the plates 3 and 4 extend with their longitudinal direction in the direction of the electrical axis A1 of the antenna. On the opposite side, the plate 3 is formed on the side of the plate 4 with an elongated hole 6 extending parallel to the long plate sides and a set screw 7 provided with a helical spring for pivoting the plate arrangement about the axis of rotation 5. On the upper longitudinal side of the plate 3, this is provided with a strip 8 bent at right angles to the plate plane, which is formed in the region of the end facing away from the pivot axis 5 with an elongated hole 9 extending in the plate longitudinal direction for a further set screw 10 for vertically pivoting the second plate 4. This adjusting screw 10, which is also provided with a helical spring, is screwed into a strip 11 of the front plate 4 which is parallel to the strip of the rear plate 3, the strip 11 being bent at a right angle to the plate surface on an adjacent longitudinal side of the plate 4 which is parallel to the upper longitudinal side of the plate 3 . In the area of the corner facing away from the set screw 10 near the pivot axis 5 of the rear plate. te 3, the front plate 4 is fixedly connected to the rear plate 3 by means of a bolt 12 such that the plate 4 can be pivoted against the plate 3 about the axis of rotation 12 formed by the bolt and perpendicular to the pivot axis 5. In order to enable this pivoting which can be carried out by means of the adjusting screw 10, the front plate 4 is also formed in the manner shown with an elongated hole 13 and a guide and locking screw 14 on the corner diametrically opposite the axis of rotation 12. In the plate arrangement shown in FIG. 2, the strip 11 of the front plate 4 forms the edge which runs parallel to the electrical axis A1 of the antenna and in the direction of this axis. The strip 11 thus represents the reference marking. This is suitably also formed with the plate 4 with an adjustable contact surface which an alignment device for setting the antenna in azimuth and elevation can be picked up and attached. The mounting of the plate arrangement on the antenna reflector 1 and the position of the plate 3 relative to the antenna reflector and the position of the plates 3 and 4 with one another is carried out by means of a direction finding process during the manufacture and the electrical testing of the antenna, that is to say prior to its installation.

Die vordere Seitenplatte 34 des U-förmigen Rah-mens 32 ist an der der Winkelgrad-Skala 35 gegenüberliegenden, ebenfalls kreisbogenförmig abgerundeten Seite mit einem kreisbogenförmig um die Drehachse 31 als Mittelpunkt verlaufenden Langloch 37 versehen, welches über eine Feststellschraube 38 die Verschwenkung 'der Grundplatte 21 im Winkelbereich der Winkelgrad-Skala 35 ermöglicht.The adjusting device according to FIGS. 3 and 4 consists of a base plate 21 with a z. B.. from about 205 to 235 degrees angle scale 22 for azimuth adjustment. In addition, the base plate 21 is provided yet with a magnetic compass 23, which, if necessary, can be replaced by a north-seeking gyro, so that the angular degree scale 22 for the azimuth adjustment in fixed relation to the north-south direction (Kompaßna - del) brought can be. The compass 23 has on its outer periphery a shoulder 24 with pointer 25, slot 26 and guide and locking screw 27. Finally, the base plate 21 also has a spirit level 28 for adjusting the horizontal. In addition, the side edge 29 of the base plate, which is adjacent to the angular degree scale 22, is chamfered and thus designed as a pointer. In the area of the other side edge 30, the base plate 21 is pivotally mounted about an axis of rotation 31 in a U-shaped frame 32 which is provided with a base 39 and surrounds the base plate 21 on four sides, the side plates 33, 34 being directed perpendicular to the base plate are. The side plate 33 is provided at its circular arc-shaped end with an angular degree scale 35 for adjusting the elevation. This angular degree scale ranges from 0 to 30 degrees, for example. In addition, the side plate 33 is formed with a contact edge oblique to the base plate, with which the setting device is coupled to the pivotable antenna construction of the receiving antenna can be. The contact edge 36 can be brought into relation to the horizontal by means of the angular degree scale 35. The front side plate 34 of the U-shaped frame 32 is provided on the opposite side of the angular degree scale 35, also rounded in the form of a circular arc, with an arcuate slot 37 extending around the axis of rotation 31 as the center, which via a locking screw 38 pivots the base plate 21 allows in the angular range of the angular degree scale 35.
