星载GNSS+BDS星间链路联合的高轨卫星定轨仿真研究
Research on high-orbit satellite orbit determination simulation with satellite-borne GNSS+BDS Inter-satellite Ka-band cooperation
摘要
Abstract
Precision Orbit Determination for High-Orbit Satellites Using Satellite-borne GNSS Alone is Challenging,While BDS Inter-Satellite Ka-band Measurements Exhibit High Accuracy and Favorable Geometric Distribution.Validation of Precision Orbit Determination Performance with Joint Ka-band and Satellite-borne GNSS Simulated Observations.Experimental results indicate that,compared to satellite-borne GNSS alone,the three-dimensional root mean square error decreased from 729.9 mm to 480.0 mm,resulting in a 34.2%improvement in orbit precision when only one BDS satellite is visible.With visibility of two BDS satellites,the three-dimensional orbit error decreased to 401.6 mm,and the radial root mean square error reduced from 269.8 mm to 137.8 mm relative to GNSS,leading to a 48.9%improvement in orbit precision.When GNSS is combined with all visible BDS satellites,the three-dimensional orbit precision can reach 269.4 mm.The introduction of BDS inter-satellite Ka-band measurements enhances the precision of high-orbit satellite orbit determination and increases orbit reliability.关键词
