摘　　要：本文在介绍正交变换算法基本原理的基础上重点介绍了为提高计算速度而采取的一些技术措施,并针对量测方程Jacobian矩阵本身引起的病态问题提出了快速正交变换阻尼因子法,通过对国内外系统的计算,验证了本文所提算法的有效性。After introducing the essential principle of fast orthogonal-transformation algorithm, this paper emphasises some techniques taken for promoting calculational speed. In order to solve the ill-corditioned problem caused by the measurement equation Jacobian matrix, fast orthogonal transformation algorithm with damping factor is proposed in this paper. The results for sevaral systems verify the efficiency of this algorithm.
