For large, complex spacecraft structural systems, it is very important to obtain structural dynamic characteristics by modal survey. For obtaining accurate modal parameters, we should select suitable excitation method, data acquisition method and data analysis method in modal survey. In particular, the accurate results will be obtained by the good selection of exictation method. This paper presents a comparison of modal parameters obtained by single point excitation and base excitation in modal survey of the truss structure.
