Flight software for rockets at SpaceX is structured around the concept of a control cycle. “You read all of your inputs: sensors that we read in through an ADC, packets from the network, data from an IMU, updates from a star tracker or guidance sensor, commands from the ground,” explains Gerding. “You do some processing of those to determine your state, like where you are in the world or the status of the life support system. That determines your outputs – you write those, wait until the next tick of the clock, and then do the whole thing over again.”
I didn't know what IMU meant but according to this[0] it's an Inertial Measurement Unit, I believe.[0] - https://en.wikipedia.org/wiki/Inertial_measurement_unit |
