It's surprising they didn't pick a RTOS.
- gosub100 2y agoWhy? What benefit would that give them?

- karlgkk 2y agoI can't tell if this a serious comment or not, but they need an OS with realtime guarantees. They have claimed to use linux in a rtos configuration, also probably have a redundancy and voting-based failover system.
- gosub100 2y agoI can't tell if this is a serious answer to the question or not, as you have answered it in terms of the question: "why the need for RTOS? -> because they need RTOS". Stop wasting time with replies like this that add no value.
- karlgkk 2y agoIf you can’t understand why the control system for SOMETHING GOING TO SPACE needs an RTOS then I can’t even begin to have a conversation with you
- karlgkk 2y agoThey did.
- MichaelZuo 2y agoHow? That was a very recent change to linux.
- wrs 2y agoIt was merged to mainline Linux last week. The patches have been usable for many years if you compile a custom kernel.
- MichaelZuo 2y agoIt’s not quite Linux anymore if it’s a custom kernel…
- karlgkk 2y agoYeah, usually it has a vendor brand slapped on it tbqh
- fennecfoxy 2y agoWhy? I doubt that Linux controls everything. I imagine it's used for the core higher level functions of the satellites themselves, but I'm sure processes running in Linux will eventually comms with lower level hardware that is indeed running an rtos or similar. In the same way that any pi project should really use i2c or spi to comms with hardware that's more purpose designed.
