摘要：
This paper presents a neural network approach for calibration of multi-path delay in GPS-based spacecraft attitude determination. Mitigating the multi-path error represents an important step towards a precise and autonomous LEO spacecraft navigation and control. The INPE and DLR cooperation activities in this direction are overviewed. The algorithm validation by a ground experiment at DLR is specially addressed. Results are presented from digital simulation based on an empirical model using series of spherical harmonics.
