利用GPS确定姿态是90年代兴起的一项新技术,GPS可为载体提供全球、全天候、精度稳定的三轴姿态,使GPS成为可同时测量位置、速度、时间和姿态甚至角速度的13维全能型敏感器。本文从理论和实验两方面研究了基于GPS的矢量观测定姿算法,包括两种基于矢量观测的定姿算法和3种形式的载波相位观测量转换为矢量观测量的方法,研究了GPS星座对此类转移精度的影响。取得了较满意的实验结果,验证了算法的有效性和理论分析的正确性。
Gesture determination using GPS is a new technology emerging in the 1990s. GPS can provide a global, all-weather, and stable three-axis attitude to a vehicle, making GPS a 13-dimensional all-around type that can simultaneously measure position, velocity, time and attitude, and even angular velocity Sensor. In this paper, we study the GPS-based attitude measurement algorithm based on GPS from two aspects of theory and experiment, including two attitude determination algorithms based on vector observations and three kinds of methods of converting the carrier phase observations into vector observations. The impact of such transfer accuracy. Satisfactory experimental results have been obtained, validating the validity of the algorithm and the theoretical analysis.
