专利汇可以提供Apparatus for measuring the attitude of an artificial satellite on the ground专利检索,专利查询,专利分析的服务。并且An upright stand has a sphere rotatably mounted on the top thereof. An artificial satellite is in turn mounted on the sphere such that its center of gravity coincides with the center of sphere. The center of the sphere also coincides with the origin of three axes of coordinates of the artificial satellite, the three axes being orthogonal to each other. A pair of optical-measuring devices are provided to measure the vertical deviations of two points on a circumference of a great circle, the center of which coincides with the center of the sphere, from a horizontal reference plane which includes the center of the sphere thereon. The aforesaid two points on the circumference of the great circle are on two orthogonal diameters of the great circle. A device is provided to calculate the attitude of the artificial satellite from the two electrical outputs of the pair of opticalmeasuring devices and an electrical reference input signal which represents the coordinates of the center of the great circle.,下面是Apparatus for measuring the attitude of an artificial satellite on the ground专利的具体信息内容。

1. An apparatus for measuring the attitude of an artificial satellite on the ground comprising; an upright support, a sphere member rotatably mounted on top of said support with said artificial satellite mounted thereon such that the center of gravity of the artificial satellite substantially coincides with the center of the sphere, a device attached to said satellite and provided around the sphere for creating a great circle therearound, a pair of electro-optical devices for optically inspecting the vertical deviations of two points positioned at different locations on the circumference of said great circle from a reference horizontal plane which includes said center of sphere thereon, and for generating an output therefrom, and means connected to receive the outputs of said pair of electrooptical devices and an electric signal corresponding to the coordinates of said center of sphere for calculating the tilt of a plane including said great circle thereon whereby the attitude of said artificial satellite may be readily determined.
2. An apparatus for measuring the attitude of an artificial satellite on the ground according to claim 1, wherein said device provided around the center of said sphere to create a great circle therearound is a cylindrical member mounted on the bottom surface of said artificial satellite such that the center axis of the cylindrical member is aligned with the center axis of the artificial satellite and the lower edge of the cylindrical member makes the circumference of the great circle.
3. An apparatus for measuring the attitude of an artificial satellite on the ground according to claim 1, wherein said means connected to receive the outputs of said pair of electro-oPtical devices and said electric signal corresponding to the coordinates of the center of said sphere includes a pair of computers for separately calculating and generating signals corresponding in amplitude to the azimuth and elevation of the artificial satellite.
4. An apparatus for measuring the attitude of an artificial satellite on the ground according to claim 1, wherein said artificial satellite includes several weight members which extend downward from the bottom periphery of said artificial satellite through respective and elongated supporting rods, said rods being located around the artificial satellite and having substantially equal angle spaces therebetween in a given plane.
5. An apparatus for measuring the attitude of an artificial satellite on the ground according to claim 1, wherein said artificial satellite includes a deep concave bore therein which extends from he bottom surface of said artificial satellite to an intermediate portion thereof in the direction of height of the artificial satellite, said artificial satellite being mounted on said sphere at the top portion of said concave bore.
6. An apparatus for measuring the attitude of an artificial satellite on the ground according to claim 1, wherein said sphere includes a great circle mark therearound for indicating said great circle.
7. An apparatus for measuring the attitude of an artificial satellite on the ground according to claim 6, wherein said pair of electro-optical devices are arranged to inspect said great circle mark provided around the wall of said artificial satellite.
8. An apparatus for measuring the attitude of an artificial satellite on the ground according to claim 1 wherein a pair of electromagnetically operable valves are mounted on said artificial satellite and when remotely operated allow a gas to either rotate or incline said artificial satellite about an axis passing therethrough.
