摘要：

The concept and implementation method of global trajectory optimization design for deep space exploration based on mission definition are presented. Firstly, the key technologies of complex task definition, adaptive model library and multi-link iterative optimization are described in detail. Then, the design technology and system implementation of the global trajectory optimization design platform for deep space exploration are discussed. Finally, based on the rich model library of the platform, the whole process flight trajectory of Chang' e-5 and other deep space exploration missions are optimized and compared. The results show that the developed deep space exploration global trajectory optimization design platform has strong adaptability and good scalability for satisfying complex tasks, which provides a reference for the development of similar software systems. © 2023 China Spaceflight Society.
