Not that kind of bus. A “satellite bus” is more of a standardized platform onto which mission-specific payloads are integrated. Saves having to design an entire spacecraft from scratch and gives you a known-good set of functionality.
So, a set of standard software RPCs (remote procedure calls) and APIs (application programming interfaces) and not another electrical signalling standard. Got it.
Thanks for the correction.
So, I guess the next question is what are you folks actually using at the electrical signalling level to talk? (If you are not allowed to say, I understand.)
