Problems solved by technology
[0004] Using the above classic star installation scheme, it is impossible to complete the star installation of the large-aperture reflector antenna with pointing structure developed by this model. The main difficulty lies in the conformal design of the reflector antenna and the satellite. The main installation surfaces are all inside the satellite and distributed in many places. Dimensional space, difficult to install and operate as a whole

The invention provides a satellite mounting and testing method for a large-aperture reflector antenna with a pointing mechanism. The method comprises the steps of 1, enabling the reflector antenna to be mounted in place in a simulation tool, and adjusting the state; 2, unlocking a pressing point of an initiating explosive device of the reflector antenna, and then unfolding in place; 3, unlocking the mounting surface of an unfolding mechanism from a fastening screw of a simulation tool, then translating, and separating from the simulation tool; 4, measuring the spatial position state of an interface on the simulation tool, and then moving away the simulation tool; 5, transferring the satellite to the position of the simulation tool in the step 1, and adjusting a satellite attitude recovery interface; 6, translating the reflector antenna to the position in the step 2; 7, fixedly connecting the mounting surface of the unfolding mechanism with a corresponding interface of the satellite; and 8, after the reflector antenna is folded in place, pressing and fixing the initiating explosive device. According to the satellite mounting and testing method, the difficulty in satellite mounting operation of a large-aperture reflector conformal design antenna is overcome, and ground testing of antenna functions and performance indexes in a system state is realized.
Description
technical field [0001] The invention relates to the technical field of satellite antennas, in particular to a satellite mounting and testing method for a large-diameter reflector antenna with a pointing mechanism. Background technique [0002] In a certain type of satellite project, it is necessary to carry out satellite installation design for a large-aperture reflector antenna with a pointing mechanism, and conduct research on the test method of the whole device state antenna. Since the antenna and the whole satellite adopt the conformal design idea, the main installation surface is recessed inside the satellite structure, and the whole satellite operation cannot be completed with the reflecting surface closed, and the antenna cannot be directly installed on the satellite installation surface. [0003] At present, the known large-aperture reflector antennas of the same type with pointing mechanism used for satellites mostly adopt the overall flat-mounted scheme, and the in...
