XTCE is a XML-based protocol description format, used to provide a machine-readable definition of the bit layout in a telemetry stream. I could use COSMOS to load this XTCE definition, but instead I just figured out what the XTCE file meant (without really reading the XTCE specification, because nobody has time for that) and wrote a quick decoder by hand.

I have never touched XTCE before this and only briefly looked at CCSDS during a rocketry project for school before deciding not to use it, so any knowledge I have about it comes from things like "google" and "[NASA presentations from 2008](https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20090017706.pdf)" and "definitely legitimately obtained specification pdfs".
