Description

technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to a large field of view and high-precision structural deformation measurement system in a simulated space environment. Background technique [0002] In order to ensure the stability and reliability of high-precision measurement satellites and space-borne equipment indicators, the load installation datum structure must have high stability characteristics, that is, the structure only produces small deformation or "near-zero deformation" characteristics in the space environment. High-stable structures represented by high-precision solid-surface antennas and precision load supports have a major impact on the accuracy of spacecraft, directly determine the performance of the entire device, and even relate to the success or failure of the mission. In the simulated space environment, high-precision real-time acquisition of its stable performance parameters is the core link a...
