Abstract

The invention relates to a spatial pointing mechanism capable of improving the environmental adaptability of a feeder, comprising a supporting part, the supporting part includes an X-direction mount, a cross bracket and a Y-direction mount, and the X-direction mount and the Y-direction mount are respectively Rotationally connected to the upper and lower sides of the cross bracket, the X-direction seat frame is rotationally connected to the cross bracket on the X axis, and the Y-direction seat frame is rotationally connected to the cross bracket on the Y axis; The X-direction seat frame is provided with an X-direction rotary joint bracket for installing the X-direction rotary joint, and the Y-direction seat frame is provided with a Y-direction rotary joint bracket for installing the Y-direction rotary joint; the upper and lower sides of the cross bracket An X-direction beam along the X-direction and a Y-direction beam along the Y-direction are respectively provided. The invention solves the technical problem in the prior art that the feeder has a bad working thermal environment due to the feeder generating heat during operation, produces relatively large thermal deformation and thermal stress, and adversely affects the performance of the feeder.

Description

technical field [0001] The invention relates to a space pointing mechanism, in particular to a space pointing mechanism capable of improving the environmental adaptability of a feeder line. Background technique [0002] With the continuous development of space technology, the on-orbit life of satellites and other spacecraft is getting longer and longer, and the real-time data requirements are getting higher and higher, which makes the demand for satellite-ground and inter-satellite data transmission continue to increase. In order to meet the requirement of increasing the amount of transmitted data, the data transmission speed is usually increased by increasing the gain of the antenna. In order to meet the establishment of a satellite-ground link or an inter-satellite link for data transmission, many antennas need to have two-dimensional rotation and tracking functions to compensate for the narrowing of the beam caused by the increased gain of the antenna. [0003] The diffe...
