摘要
本文深入探讨了双星定姿方法,仅利用2颗GPS卫星进行了实际的双星定姿试验,文中综合应用长短基线法和序列优化法求解整周模糊度。试验结果表明,当基线长约1m时,该方法定姿成功率达90%以上,定姿均方差优于0.5°。
The method of attitude determination with double satellites is discussed indetail in the paper, and the actual experiment of attitude determination with onlytwo GPS satellites is conducted. The long-short baseline method and sequenceoptindzation method are synthetically used to estimate carrier phase ambiguity.The experiment results indicate that the success rate of attitude deterndnationexceeds 90% and the mean square error of attitude can be less than 0.5°, whenbaseline length be 1 m around.
