Breakthrough hybrid model restores orbit accuracy for BeiDou-3 satellites
Tokyo, Japan (SPX) Jun 12, 2025 Two BeiDou-3 navigation satellites once plagued by orbit inconsistencies are now operating with significantly improved accuracy, thanks to a novel hybrid modeling technique that better accounts for solar radiation pressure. Researchers integrated a physically based Adjustable Box-Wing (ABW) model with the empirical ECOM2 framework, cutting laser ranging residuals by over 60% and improving real-t
