Research of Adjustment by the Method of Least Absolute Deviation

In the actual observation of the errors,small rough errors sometimes occur,which seriously distortes or badly influenced the results of the least-square method.However,compared to the least square method,adjustment by the method of least absolute deviation is less affected by rough errors.In this paper,the mathematic model of the adjustment by the method of least absolute deviation,the un-uniqueness of solution,and the comparison of the abilities for adjustment by the method of least absolute deviation and least square method to be resistant to rough errors will be presented.
