Abstract: The article reviews the background, current situation, and demand of photogrammetry for thermal deformation of space-borne antenna, with elaboration of related principles and methods, together with systematic summarization and discussion of three photogrammetry methods used both at home and abroad, namely single camera external, single camera internal and multi camera internal. The research on atmospheric thermal deformation measurement technology carried out by Xi’an Institute of Space Radio Technology was emphasized. Subsequently, based on the development trend of space-borne antenna towards larger size, higher accuracy and higher stability, technical issues and future development directions of thermal deformation measurement technology needing to be further considered are proposed.
