双星姿态测量中确定整周模糊度的新方法

摘要

针对双星姿态测量中整周模糊度解算这一关键问题,提出了一种新的双星整周模糊度解算方法--天线反转法.其基本思想是,在静态初始化过程中将副天线绕主天线反转了180°.模拟算例表明,该方法能够快速可靠地解算出双星整周模糊度.%Integer ambiguity resolution is the key step to use carrier phase measurements to determinate the attitude of object for the double GEO Satellites System. A new method of ambiguity resolution for attitude deterrnination was presented, that is, antenna inversion technique. The idea of antenna inversion was to rotate the slave antennae 180°around the master antenna during the static initialization. A simulation showed that the method was able to rapidly get the integer ambiguities with very high success rate.
