利用GPS载波相干测量技术确定空间飞行器姿态的研究

Study about Spacecraft Attitude DeterminationUsing GPS Carrier Phase Interferometric Technique

Ｇ Ｐ Ｓ载波相干测量技术存在的主要技术难题是载波相位整数模糊度的解算、导航星观测几何的优化等问题， 本文基于差分技术研究了这项技术在空间飞行器姿态确定方面的应用。

The paper discusses basic technical problem s existed in the \%GPS\% carrier phase interfermetry for spacecraft attitude det ermination to resolve the integer ambiguity resolution of the \%GPS\% carrier ph ases and as well as to optimize the observation geometry of \%GPS\% navigation s atellites,and studies the application of the \%DGPS\%-based carrier phase measur ement in spacecraft attitude determination.
