Gross Error Location by means of the Iteration Method with variable Weights

The iteration method with variable weights would be an effective method for the location of gross errors in the adjustment.After a general view of several different and available weight functions of this method a new weight function and a corresponding test quantity are developed based on the a posteriori variance estimation of the least squares.The advantages of the suggested method are justified through a comparative investigation of the different weight functions.The introduction of this weight function into danish method can also produce a good result.
