基于模糊度的姿态测量仿真与实现

Simulation and Realization Based on Attitude Determination of Ambiguity

在分析姿态测量发展的基础上,对模糊度求解的LAMBDA算法进行深入的研究,对序贯条件最小二乘和模糊度去相关进行详细的理论分析、公式推导和实例论证,并实现了基于模糊度的去相关前后搜索空间和方差比较的仿真验证,可为姿态测量的后续发展提供技术参考和研究方向。

Based on the analysis about the development of attitude determination,Least-Square Ambiguity Decorrelation Adjustment(LAMBDA),which is a method of ambiguity resolution in real time,is made further study.The thesis presents detailed theoretical analysis,formula derivation and example verification for sequential conditional Least Squares estimation and ambiguity decorrelation,and the simulations of search space before and after decorrelation and comparison of variance based on the ambiguity are verified.All these researches can provide technology reference for the future development of atti tude determination.
