Not sure about a mission as old as voyager, but most modern missions use CCSDS protocols, which are open and available online.
But just because you know the protocol dues not mean you have enough information to send a valid command. The commands are wrapped in a common protocol, but the commands themselves are typically mission-specific and definitely not made public.
Here’s an example of someone unaffiliated with the mission decoding JWST telemetry. While they were able to identify the packets defined per CCSDS protocols, they do not know the actual content of the packets, which are mission specific.
Thanks for the information. It's more just having fun decoding some telemetry protocol and maybe making some interesting graphs. Like maybe there's some interesting things they don't mind you knowing.
> And as someone else mentioned, the biggest hurdle with getting a command to voyager is access to a 70 m dish. Not many of those floating around…
