Abstract ：Control network with additional gyro-side is useful for accuracy of underground traverse，traditional meth­od for control traverse with additional gyro-side is to apply least squares estimation to compute parameters of model tak­ing gyro azimuth and observation data of traverse as variables. However，the method based on least squares estimation can not take into account the fact that both observation vector and coefficient matrix have random error，and the work environ­ment may lead that observation data has gross error which has influence on computing parameters of model. To overcome the shortage of traditional method，solution for control traverse based on total least squares is proposed in this paper. To take into account the condition that both observation vector and coefficient matrix of mathematical model have random er- ror，and to get over the influence that gross error existing in observation vector and coefficient matrix have，the iterative al­gorithm based on Lagrange function is presented to solve the problem，and Huber function is also applied to overcome the influence that gross error has on computing the parameters. At the last of paper，an instance of control traverse with gyro -side is used to demonstrate the proposed solution to be feasible，and differences of accuracy among the proposed solution and traditional algorithms are also discussed.
