一种基于天线布局的姿态测量算法研究

摘要

该文针对姿态测量过程中求解整周模糊度计算复杂度高的问题，提出一种基于天线布局的姿态测量方法。该方法在一定的测量误差下，采用特定的方式配置姿态测量天线组，通过天线配置的约束信息确定载波相位的整周模糊度差，并使用短基线和中基线分别进行姿态粗测和精测，达到快速姿态测量和提高精度的目的。使用这种方法进行飞行器姿态测量时可以不必求解整周模糊度，避免了复杂的整周模糊度搜索算法，进而提高了姿态测量速度，该方法非常适用于飞行器的快速测姿。%In order to solve the problem of high computational complexity of the ambiguity in attitude measurement, a new attitude measurement method based on antenna configuration is proposed. In a certain range of measurement error, the antenna array for attitude determination is properly configured, the integer ambiguity of double difference carrier phase is determined by the constraint information of antenna configuration. Short-baseline and middle-baseline are used for coarse and precise attitude measurement. This method for aerocraft attitude determination does not need to solve the ambiguity. It avoids the use of complex ambiguity search algorithm and improves the speed of attitude determination, it is suitable for fast attitude measurement of aerocraft.
