4 End-to-End Assessment of Artemis-1 Development Flight Instrumentation 33 Fig. 4.9 Effect of Modification of Anti-Aliasing Filter on Spectral Content 4.3 Conclusion Flight missions are a critical but expensive step in the validation of models and critical to ensuring human safety in space travel. Confidence in flight measurements begins with confidence in the DAQ system used for measurement. As this study illustrates, full system knowledge of a given system is necessary to define DAQ parameters. An end-to-end system assessment proved to be a very useful tool to investigate probable problem areas in the current DAQ set-up for Artemis-1. The methodology presented herein, gives the engineer the necessary information to make well informed decisions about how to fix potential problems and ensure successful execution of the flight test objectives (FTO). It is clear that an end-to-end assessment such as this would be a very useful step in the initial phase of DAQ system design. Flight missions will continue to present unique challenges for test engineers, but by using the right tools early in the process we can still have high confidence in our measurements. Acknowledgments Special thanks to Joel Sills at NASA’s Johnson Space Center (JSC) for his guidance and continued support of this assessment. In addition to JSC, this assessment relied on input from NASA Marshall, Langley, and Kennedy Space Center. Special thanks to all NASA employees and contractors who made this work possible.
