Workmanship vibration test of the SAS-B spacecraft

The occurrence of a technical problem made it necessary to remove the transmitter from the SAS-B spacecraft. The transmitter was repaired and reinstalled in the spacecraft. After this operation it was necessary to test the mechanical properties of the reassembled spacecraft in a vibration test to be conducted near the spacecraft launching place on the San Marco Range in the Indian Ocean. A vibration system was, therefore, sent to San Marco. The design of the vibration system is discussed, giving attention also to alternative solutions for conducting the required tests.
