Abstract: The structured total least norm (STLN) algorithm was used to estimate the mass and center of mass parameters.This method has three advantages comparing with the existing methods:the dynamic equations of satellites were not simplified;practically inaccurate thrust force and torque were not used in the equations,sensor noise was considered.Theoretical analysis shows that the STLS solution is maximum likelihood estimate when the sensor noise is Gaussian.Simulation confirms the usefulness of the method.
