Abstract:On the basis of the total leastsquares(TLS) data processing theory and an iterative algorithm for TLS, firstorder partial derivative of the nonlinear model was determined by using Taylor formula and the error magnitude of the results was derivated. The method was applied to the TLS precision evaluation, and the method for reliability testing is proposed. The experimental results verify the feasibility of the method in TLS precision evaluation.
