As spacecraft, satellites, and space probes are often one-of-a-kind systems, the final flying space system is also the prototype. To secure the good operation of the satellite after the launch, all satellites undergo extensive environmental testing. This is a risky business!
If a satellite is structurally designed to withstand loads of the launch, it is important that a qualification test (whether it is a pyro-shock, vibration or acoustic test) does not “over-test” the satellite above the specifications. The risk of over-testing would lead to component failures or, worse, a launcher explosion. Hence the importance of having these qualification testing campaigns fully under control to reduce the risk for over-testing.
