Questions and Answers

What is the purpose of functional testing in system integration and test?

  • To characterize the payload or system
  • To check if subsystems work together (correct)
  • To demonstrate the final system integration
  • To perform environmental testing
  • Why might combined functional and environmental testing include spacecraft level thermal vacuum?

  • To ensure the safety of ground systems like propulsion and attitude control
  • To characterize the payload or system
  • To demonstrate the final system integration
  • To check performance alterations due to the space environment (correct)
  • What is the primary reason for using 'stimulators' for sensors like sun & earth sensor, or star tracker in ground testing?

  • To simulate spacecraft level thermal vacuum
  • To conduct environmental testing
  • To ensure operational tests of electrical/electronic systems (correct)
  • To avoid altering performance characteristics
