Abstract

A six-degree-of-freedom position and posture adjusting device for satellite antenna includes three sets of antenna mounted actuating assemblies mounted on the base, The three sets of actuator assemblies are evenly distributed on the pitch circle; Each set of actuator assembly comprises two actuators, the driving axes of the two actuators are at an included angle of 60 DEG, the upper ends of the two actuators are connected to the same adapter bracket A, and the lower ends of the two actuators are respectively connected to corresponding adapter brackets B; And the upper and lower ends of each actuator are respectively provided with flexible hinges. The invention can realize the six-degree-of-freedom posture adjustment of the satellite-borne antenna and compensate the position and posture deviation of the antenna on the orbit. The invention is applicable to satellite-borne antenna systems which require high position and attitude accuracy such as reflector antenna, measurement and controlantenna and data transmission antenna.

Description

technical field [0001] The invention relates to the aerospace field, in particular to a six-degree-of-freedom pose adjustment device for a spaceborne antenna. Background technique [0002] In the field of modern satellite applications, mission modes such as on-orbit communication transmission, microwave remote sensing, electromagnetic reconnaissance, and optical detection play an important role. Satellites performing similar missions need to be equipped with high-precision antennas. Since the position accuracy and pointing accuracy of the antenna directly affect its performance, in order to improve the overall performance of the satellite, the requirements for the antenna's on-orbit pose accuracy are getting higher and higher. [0003] When a spacecraft is launched into orbit, it will experience a harsh vibration and noise environment, and the installation accuracy of the antenna will deteriorate accordingly. When a spacecraft flies around the earth, its orbital position an...
