| 摘 要： | 本文导出了大地网参数平差中计算权系数矩阵的递推公式,并通过实例说明它在经典平差和自由网伪逆平差中的应用。由于这一方法无需组成法方程组,所以可作为无法方程组的参数平差法的计算基础。 由于本方法具有很高的精度,又比传统方法简便,所以它在平差计算中将有广泛的应用前景。

| Abstract: | In this paper a sequential formula used to compute weight coefficient matrix for adjustment of geodetic networks is deduced.Its applification is; shown through the examples in the clasical adjustment and the pseudo-inverse adjustment of free networks. This method, without the need to form the normal equation,can be served as the basis for the non-normal equation adjustment by parameters.This highly accurate method, that is simpler and more convenient than the classical ones, has the wide application prospect. |
