Abstract
The ultra-high stability thermal control design for the transit telescope payload of the Space Origin Exploration Program ET2.0. was conducted by leveraging the heat capacity of the controlled system and the heat transfer relationships, the amplitude of temperature fluctuations of the controlled system is gradually reduced to ensure ultra-high precision and excellent temperature stability for both the telescope and the detector. And then a test in the ground simulation system for the space environment was conducted to simulate the real thermal environment of the transit telescope, primary focal plane, and detector, and implemented multi-stage temperature control on the detector substrate. The final test results showed that the temperature fluctuation was controlled within ±3 mK, meeting the index requirement of ±10 mK, and it also exhibited a certain ability to resist environmental temperature fluctuations.
