ACSSatellites are usually exposed to acoustic irradiation on huge, low-reflection testbenches using electric-pneumatic high intensity horns in varying frequency ranges. The Acoustic Control System (ACS) regulates the sound excitation by means of closed loop algorithms, allowing the user to simultaneously record microphone and vibration signals. Sine ReductionAnother test scenario for the final testing of satellites involves
vibration tests employing swept-sine excitation using shakers. SRSThe Shock Response Spectrum (SRS) is available to the user for providing detailed analyses of a satellite's transient excitation and shock excitation. |
