Abstract
A novel Adaptive Parallel Feedback-Accelerated Picard Iteration (AP-FAPI) method is proposed to meet the requirements of various aerospace missions for fast and accurate orbit propagation. The Parallel Feedback-Accelerated Picard Iteration (P-FAPI) method is an advanced iterative collocation method. With large-step computing and parallel acceleration, the P-FAPI method outperforms the traditional finite-difference-based methods, which require small-step and serial integration to ensure accuracy. Although efficient and accurate, the P-FAPI method suffers extensive trials in tuning method parameters, strongly influencing its performance. To overcome this problem, we propose the AP-FAPI method based on the relationship between the parameters and the convergence speed leveraging parallel technology. The proposed method ensures the best possible efficiency in prescribed accuracy. Three typical orbit propagation problems are illustrated to validate the high performance of the proposed method. Numerical simulations show that the AP-FAPI method is more accurate and efficient than the finite-difference-based and the P-FAPI methods.
