Study on HUBS satellite mission architecture and the key technologies of mechanical and thermal engineering

The realization of HUBS scientific objectives requires space-based observation, therefore the design and construction of satellite mission architecture is particularly important. Satellite mission architecture mainly includes launch, orbit entry, establishment of initial detection state, start-up and operation of working modes, etc. In addition, in order to ensure the imaging detection quality of x-ray payload, the long-term defocus/off-axis control quantity better than ±1mm needs to be maintained between the x-ray focusing optical system and the superconducting transfer edge sensor array over a space span of nearly 3m. For low thermal conductivity materials, the optical system also needs to ensure the temperature control index of 20±2°C, in order to jointly provide support for imaging index requirements of the thermal peripheral conditions. Based on the introduction of the satellite mission architecture, this paper will also discuss the solutions of the aforementioned key technologies.
