This paper deals with a method to determine dynamic characteristics of space structures by component modal tests. This method uses additional mass and stiffness to consider the effect of untested components. Modal test results depend on a location with additional mass and stiffness. We select optimal location using information about variations of two masses. These masses are found by reducing mass matrices of a tested component and a structure to an arbitrary degree of freedom. It is effective to select the location with large modal amplitude of structure modes for the accuracy of measured frequency and mode in component modal tests. A numerical example is given to show the effectiveness of the method.
