Spacecraft Integration & Test: An undergraduate course in systems engineering practiceMichael SwartwoutSanjay JayaramSaint Louis UniversityThe teaching of good systems engineering practice to undergraduates requires thatstudents gain practical experience in designing, assembling and operating complexsystems. The lessons learned from success and failure are a powerful aid tounderstanding, but it is very difficult to find appropriately-scoped projects that cansupplement classroom activity. The need for practical experience and the challenges increating opportunities are very evident in the area of spacecraft integration & test (I&T):a large fraction of a space project's budget and schedule are devoted to I&T, and many in-space failures could be avoided through proper testing.Faculty at Saint Louis University (SLU) have created a candidate course for trainingundergraduates in systems engineering through integration & test. This course blends thetheoretical principles of integration & test with the practical constraints of preparing asmall student-built spacecraft for launch. It introduces four heurestics of spacecraft I&T:(1) the ground, launch and space environments are unforgiving and spacecraft are proneto failure; (2) complex systems rarely (if ever)work properly the first time they areassembled; (3) there will never be enough time or money to "properly" test everything;(4) the driving force behind most decisions in space system development is the fear offailure. From these first principles, we can explain the rationale behind and processesused in major environmental and functional testing. We also can justify the developmentof massive systems for documentation.In parallel with the theoretical work, students are responsible for designing, conductingand analyzing spacecraft acceptance tests for a small satellite, and preparing the testreports for evaluation by NASA. NASA's Educational Launch of Nanosatelllites (ELaNa)program appears to be an ideal platform for improving space systems education.In this paper, we will outline our approach for teaching spacecraft integration & testthrough a classroom and laboratory exercise. We will report on the challenges in scopeand schedule as we attempted to keep the program within a 3-unit, 1-semester course.Results of the student, faculty and industry assessments will be reported. Finally, we willalso examine whether this approach could be used in other programs and/or on projectsother than student satellites.
