边角后交粗差的一种检查方法

A Method Checking Rough Error of Side-Angle Resection

利用间接平差的原理 ,在列误差方程时增加了一个距离比例系数q并与待定点一起进行平差计算 ,通过q值大小来判断是否有粗差的存在 ,弥补了传统方法无多余观测时 ,计算本身无法检查的缺陷 。

A ratio coefficient q of distance is added while eror equations are set up by the principle of the indirect adjustment.By using q and a waiting point,average errors can be calculated.It is judged q that if an coarse error exists or not.The defect is then compensated that this calculation itself can't be rechecked when there aren't surplus observations by the traditional methods and a calculation example is presented to verify the above mentioned method.
