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。
