摘要: 摘 要: 由于地基定轨系统的局限性,本文提出了基于GNSS的高轨卫星定轨方法,并设计实现了高轨卫星天基定轨仿真软件。结合高轨卫星天基定轨的特点和GNSS的建设现状,研究了卫星可见性算法和星间观测模型,综合轨道积分和Kalman滤波方法的优点,提出了确定高轨卫星轨道的积分滤波方法。仿真结果表明基于GNSS完成天基定轨增加了卫星的观测量,提高了定轨精度。最后在理论研究的基础上,自主开发了集STK、Matlab和Visual C++为一体的高轨卫星天基定轨仿真平台。本文的成果为将我国北斗系统应用于高轨卫星天基定轨提供了理论上参考依据和理想的模拟工具。

Abstract: Abstract: As the limitations of ground orbit system, this paper presents a method of orbit determination of GEO satellite based on GNSS, and designs an orbit determination of GEO satellite software. Combination of orbit determination of GEO satellite characteristics and construction of GNSS, the satellite visibility algorithms and inter-satellite observation model are discussed, integral Filter method is proposed to determine the orbit of geostationary satellite to make use of the advantage of orbit integral and Kalman filter method. Simulation results show that orbit determination of GEO satellite based on GNSS can increase the satellite observations and improve the accuracy of orbit determination. Finally, the paper develops a space-based orbit determination of GEO satellite simulation platform with STK, MATLAB and Visual C++. The outcomes of this paper will provide theoretical reference and ideal simulation tool for the application of Compass on orbit determination of GEO satellite.
