病态方程组的分块迭代法及其在GPS整周模糊度估计中的应用

Iteration Method in Blocks and Its Applications in the Estimations of the Whole Period Fuzzy Measure of GPS

从求解严重病态线性代数方程组的实际出发,通过分离复共线矩阵列来将未知参数分组交替地作最小二乘估计,得到了一种新的迭代解法——分块迭代算法,并给出了迭代格式的收敛性证明。最后通过实例验证了上述结论。

This paper presents a new iteration method for solution morbity linear equations-- the iteration solution in blocks. The iteration can alternately est imate the unknown parameters in the least square estimations by partitioning mat rices of complex dependence. At last the above result is checked by example.
