❓ Frequently Asked Questions
What is flight software?
The onboard programs that run on a spacecraft's flight computer to control attitude, propulsion, power, comms, and routine operations in real time.
What does GNC stand for and what does it do?
Guidance, Navigation, and Control; it determines the vehicle's path and orientation by estimating its state, planning maneuvers, and issuing commands to actuators.
How do flight software and GNC interact in a mission?
Flight software provides the execution environment and interfaces; GNC algorithms run within it, using sensor data to estimate state, decide maneuvers, and command actuators.
What is Systems Integration in this context?
The process of making hardware, software, sensors, actuators, and ground systems work together reliably, ensuring correct interfaces, timing, data flows, and safety.
How are flight software and GNC validated and tested?
Through simulations, models, hardware-in-the-loop testing, unit/integration tests, fault injection, and formal verification where feasible; helps validate performance before flight.
