The results by these two approaches are the same as by QUAD(Quasi Accurate Detection), and the observations with gross error no longer affects the adjustment.
结果表明，两种方案与“拟准检定法”具有相同的效果，具有粗差的观测值在平差时不起作用。

The iteration method with variable weights would be an effective method for the location of gross errors in the adjustment.
