Prolonged periods from conception to deployment of a satellite can undermine a time
dependent mission. Currently, the timeline for a new satellite to reach deployment is on
the order of years. The need for a more efficient process is evident and has lead to innovations
at every aspect of satellite design and pre-launch testing. One such example is the
development of panels and components that are prefabricated for space flight and capable
of assembly in a variety of configurations. However, all final systems regardless of component
qualification must be validated for space flight. Current qualification testing can take
weeks to years. An ultrasonic technique based on the energy of a transmitted wave across
the connection is intended either as an alternative to traditional vibration=qualification testing
or as a precursor to in-situ monitoring of panel-to-panel connections. Transmitted elastic
wave energy is used to assess the integrity of the connection in reference to an initially
established baseline. An experiment was conducted on a functional satellite to test the feasibility
of deploying this test method under realistic circumstances. A second experiment was
conducted to test the repeatability of the test method and to find an appropriate range of test
