Questions and Answers

What is the primary purpose of the Guidance, Navigation and Control (GN&C) system?

  • To provide instructions for the entire mission in a single load
  • To manage the spacecraft's position and attitude throughout all flight phases (correct)
  • To separate mission segments due to memory limitations
  • To test programmed flight segments before loading them into the system

    • What is the reason for separating mission segments into different loads?

  • To accommodate the memory limitations of the General Purpose Computers (correct)
  • To ensure redundancy in case of system failures
  • To optimize the performance of the guidance and control algorithms
  • To allow for software updates between mission segments

    • Which subsystem of the GN&C system is responsible for determining the desired spacecraft position and attitude?

  • Control Subsystem
  • Navigation Subsystem
  • All subsystems contribute equally
  • Guidance Subsystem (correct)
