Contents I. Introduction
With the continuous improvement of the development requirements of spacecraft models in China, it is very urgent to measure the spacecraft temperature in the ground simulated space vacuum thermal environment, and to monitor the space temperature of the spacecraft and the spacecraft health status diagnosis in orbit. Optical fiber temperature sensing technology has the advantages of anti-electromagnetic interference, less wire harness, light weight and large spatial distributed measurement, which can meet large-scale complex satellites and large exposed structural parts in aerospace field (such as mesh antenna, truss structure, mechanical arm, paraboloid). Antennas and various special deployment mechanisms) application requirements for vacuum thermal testing and on-track health status diagnostics.
