Abstract
Abstract This invention relates to the steering of telecommunication antennae, and particularly to the mountings therefor. These mountings are used for supporting an antenna to allow communications to be established with a geostationary satellite i.e., one which is stationary in relation to the earth. The invention provides that the structure associated with the antenna be mounted at three points on the steering mounting, and the latter rests on the ground. That one of these points which is situated at the apex of said structure is provided with a bi-directional joint which allows the antenna to pivot about an axis XX in azimuth and an axis YY in elevation: these axes lying orthogonally to one another in a plane perpendicular to the axis ZZ of the antenna. The bi-directional joint aforementioned is mounted to pivot on the base mounting about the axis ZZ of the antenna itself.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
152 words
A steering mounting for a telecommunication antenna used to track a geostationary satellite, said mounting comprising a recticulate rigidifying structure including a generally symmetrical frame having an apex support point, a reflector assembly secured to said rigidifying structure, and means for supporting said reticulate structure on the ground, said supporting means including means for supportingly engaging said reticulate structure at three points, one of said points being situated at the apex of said reticulate structure, said means for supportingly engaging said reticulate structure including bi-directional joint means at said apex for allowing the reticulate structure to pivot at the apex about an axis XX in azimuth and an axis YY in elevation, said axes lying orthogonally to one another in a plane perpendicular to the axis ZZ of symmetry of the reticulate structure, and means mounting said bi-directional joint means on said supporting means for pivotal movement thereon about the axis ZZ.
Claim 2
Dependent Claim
152 words
A steering mounting for a telecommunication antenna used to track a geostationary satellite, said mounting comprising a recticulate rigidifying structure including a generally symmetrical frame having an apex support point, a reflector assembly secured to said rigidifying structure, and means for supporting said reticulate structure on the ground, said supporting means including means for supportingly engaging said reticulate structure at three points, one of said points being situated at the apex of said reticulate structure, said means for supportingly engaging said reticulate structure including bi-directional joint means at said apex for allowing the reticulate structure to pivot at the apex about an axis XX in azimuth and an axis YY in elevation, said axes lying orthogonally to one another in a plane perpendicular to the axis ZZ of symmetry of the reticulate structure, and means mounting said bi-directional joint means on said supporting means for pivotal movement thereon about the axis ZZ.
Claim 3
Dependent Claim
117 words
A steering mounting according to claim 1, wherein said supporting means comprises a triangular-based pyramid frame resting on the ground at three points and having an apex at which said means for mounting said bi-directional joint means is located adjacent the apex of the reticulate structure of the antenna, said supporting means including two extensible jacks respectively pivotally mounted at one end at two corners of said pyramid frame and at their opposite ends to said reticulate structure at the other of said three points, and an elongated link pivotally connected at one end to one of said jacks adjacent the said other end thereof and to the other of said jacks adjacent its said one end.
Claim 4
Dependent Claim
28 words
A steering mounting according to claim 2 wherein said reticulate structure includes a pair of tripod frame elements respectively connected to said jacks at said opposite ends thereof.
Claim 5
Dependent Claim
38 words
A steering mounting according to claim 2 wherein said pyramid frame is formed by three tubular elements, one of which, located at the other of the corners of said pyramid frame from said jacks, is adjustable in length.
Claim 6
Dependent Claim
26 words
A steering mounting according to claim 2, wherein said bi-directional joint means by which the apex of said reticulate structure is supported comprises a universal joint.
Claim 7
Dependent Claim
39 words
A steering mounting according to claim 2 including means for controlling said jacks comprising motors and sequential control means including two microswitches and rotationally driven cam means, the position of said micro-switches being adjustable relative to said cam means.
Claim 8
Dependent Claim
53 words
A steering mounting according to claim 2, wherein the sequential operation of the jacks by said motor and switches causes rotational movement which, in combination, allows the antenna to be rotated about said XX, YY and ZZ axes, whereby said antenna is positionable anywhere in space from the apex of the reticulate structure.
