Crew Dragon Simulated Flight Ensures Hardware, Software are Ready for Missions

SpaceX recently powered up its Crew Dragon avionics test bed at its facility in Hawthorne, California, by simulating a crew flight to the International Space Station. During the avionics functionality check, engineers were able to make sure the spacecraft’s hardware and software worked well together in a flight-like environment. The avionics are known as the brains of a spacecraft, controlling all the critical automated operations of a flight.

“It may not sound exciting, but it’s a really, really important tool. We can basically fly the Crew Dragon on the ground — flip the switches, touch the screens, test the algorithms and the batteries – all before testing the avionics system in flight,” said Hans Koenigsmann, vice president of mission assurance for SpaceX. “It’s important to get the avionics right before putting it into the capsule.”

The SpaceX avionics test bed is similar to the Shuttle Avionics Integration Lab, or SAIL, in Houston, which was used throughout NASA’s Space Shuttle Program to test the interaction of hardware and software before modifying code on the vehicles for flight.
