Abstract:
As another flagship telescope mission after the Hubble Space Telescope, the James Webb Space Telescope (JWST) is currently the largest space telescope in the world. The JWST is equipped with large-sized and high-precision optical devices that must be operated in a deep cryogenic environment. However, the traditional test approaches and equipment cannot meet its development needs. To balance the mission development cycle, cost, and overall reliability, the mission JWST has adopted a different test verification method from those of traditional spacecraft, which has combined integrated model simulation verification with test verification. In this paper, survey and analysis on the subsystem level and system level test verification methods of the JWST in addition to the description to the modification of its ground test system equipment, were reviewed. The review may provide a reference for the development of future large-scale satellite testing technology in China.
