Several modal test techniques were employed in the recently completed modal test on a meteorological spacecraft. The primary technique, which was required by the customer, was the classical multiple-shaker sine-dwell method. Although this method is quite time-proven, it takes considerable time to perform the test. Very good results were obtained from this method. The results are used as a basis for comparison with the results of state-of-the-art, less proven but more time efficient test methods. The paper presents the results of the multiple-shaker sine-dwell test, and comparison is made with the results of both single-point random and multiple-point random tests. The paper concludes with a short discussion of the relative merits of each technique.
