摘要/Abstract

摘要： 本文的研究内容是利用GPS接收机的导航信息精确确定接收机载体航天器的轨道根数。本文给出了为确保10m量级的定轨精度所必需的精确坐标系变换与时间系统变换公式,提出了采用GPS接收机的导航信息与摄动运动方程式外推的组合导航方法,以保证接收机天线被短期遮挡时导航仍能正常运行。

Abstract: This paper proposes an accurate orbit determination technique to accurately determine orbit elements of a spacecraft equipped with a GPS receiver according to navigation messages from the receiver. Accurate coordinate system and time system transformations necessary to guarantee the orbit determination accuracy of the order of 10m are presented. A combined navigation method using navigation messages from receiver and the recursive formula of the perturbation motion equation is adopted, and the navigation can still operate normally even if antennas of the receiver is obscured in a short duration.

Key words: orbit determination , orbit elements
