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 star installation and testing method for a large-diameter reflective surface antenna with a pointing mechanism, comprising the following steps: 1. The reflective surface antenna is installed in place in a simulated tooling, and the state is adjusted; 2. The reflective surface antenna is unlocked at the compression point of the pyrotechnic product , and then unfold in place; 3. Unlock the mounting surface of the deployment mechanism and the fastening screws of the simulation tooling, then translate and separate from the simulation tooling; 4. Measure the spatial position of the interface on the simulation tooling, and remove the simulation tooling after completion; 5. The satellite is transferred to Simulate the position of the tooling in step 1, and adjust the satellite attitude recovery interface; 6. Move the reflector antenna to the position in step 2; 7. The mounting surface of the deployment mechanism is connected and fixed with the corresponding interface of the satellite; 8. After the reflector antenna is retracted in place, Press and fix the pyrotechnic material. The satellite installation and testing method in the present invention overcomes the difficulty of installation operation of the large-diameter reflective surface conformal design antenna, and realizes the ground test of the antenna function and performance index under the system state.
Description
technical field [0001] The invention relates to the technical field of satellite antennas, in particular, to a satellite installation and testing method for a large-diameter reflective surface antenna with a pointing mechanism. Background technique [0002] In a certain type of satellite project, it is necessary to carry out a satellite installation design for a large-diameter reflector antenna with a pointing mechanism, and conduct a research on the antenna test method for the whole device. Due to the conformal design of the antenna and the whole satellite, the main installation surface is concave inside the satellite structure, and the whole satellite operation cannot be completed with the reflective surface retracted, and the antenna cannot be directly installed on the satellite installation surface. [0003] At present, the well-known large-diameter reflective surface antennas with a pointing mechanism of the same type used for satellites mostly adopt the overall flat-mo...
