Abstract:The method of converting linear Gauss-Markov (GM) model to linear errors-in-variables (EIV) model was given, an ordinary total least squares (TLS) adjustment algorithm were introduced as an alternative method for converted EIV model. Extended TLS methods of weight TLS, mixed ordinary LS and TLS, constrained TLS estimators with computational schemes were introduced as well. A typical geodetic control network adjustment and a curve fitting data experiments are given to compare the adjustment results in accuracy and computation efficiency by TLS and tradi
