卫星轨道理论的深入研究及其在定轨、预报和参数测定中的应用

An Intensive Research of Satellite Orbit Theory and Application in Orbit Determination,Forecast and Parameter Estimation

自从1957年第1颗人造地球卫星Sputnik升空以来，人类进入空间时代已过半个世纪，这50多年中卫星技术日趋成熟．这篇论文根据作者在博士研究生阶段参加的3项课题撰写而成．这3项课题涉及了人造地球卫星轨道理论及应用的几个主要方面，具有一定的代表性，也能够展示目前卫星轨道研究的主要内容、手段以及在应用领域中的重要作用．

It has been over half a century since the launch of the first artificial satellite Sputnik in 1957, which marks the beginning of the Space Age. During the past 50 years, with the development and innovations in various fields and technologies, satellite application has grown more and more intensive and extensive. This thesis is based on three major research projects which the author joined in. These representative projects cover main aspects of satellite orbit theory and application of precise orbit determination （POD）, and also show major research methods and important applications in orbit dynamics.
