Researchers from Wuhan University have developed a new Uncertainty-Aware Filtering (UAF) algorithm that significantly enhances spacecraft autonomous navigation in deep-space environments characterized by weak gravity, strong perturbations, and limited prior knowledge, which is published in the Chinese Journal of Aeronautics (https://doi.org/10.1016/j.cja.2025.103971). The method shows clear advantages over conventional Extended Kalman Filter (EKF) and Unscented Kalman Filter (UKF) approaches and has been validated using simulations of China’s Tianwen-2 mission to asteroid 311P/PANSTARRS.

Quantum computing offers a promising pathway for accelerating large-scale scientific simulations, but applying it to computational fluid dynamics remains difficult. A new quantum TLFS-LBM framework reported in the Chinese Journal of Aeronautics (https://doi.org/10.1016/j.cja.2026.104176) introduces a fractional-step correction, a coordinate-based streaming matrix, and a multi-circuit strategy to enable practical incompressible-flow simulations on non-uniform meshes and complex boundaries while reducing quantum-circuit resource demands.

Small target detection and tracking in UAV remote sensing images are key tasks in fields such as security patrols and traffic monitoring. Recently, a framework called the Cropped Target Detection and Tracking Framework, through cropping and random sampling strategies, significantly improves real-time performance while ensuring small target positioning accuracy and tracking robustness, which is published in the Chinese Journal of Aeronautics.
