Reflector Surface Precision Measurement and Adjustment of Cable-Truss Combined Structures,To observe the universe more clearly, it is a good strategy to put an antenna in space. The Hubble space telescope in the USA is an example. In the harsh environment of space, it is difficult to maintain the surface precision of the antenna, which is one of the most crucial indicators to evaluate the performance of the antenna.
