libccsds

A library to handle several CCSDS routines

Why? Throughout my projects, I very often ended up needing some common routines (eg, deframing, demuxing) to deal with CCSDS protocols. There was no library fitting this purpose already (at least, not in C/C++) and copy-pasting code between projects in the long run is... Not a good thing so I decided to put all that in a nice lightweight library!

Features

Currently this library provides :

  • Defined data structures and parsing methods (from binary) for CADU, VCDU, M-PDU, and CCSDS frames
  • A CADU deframer, based on a sync machine for better performances (based on this)
  • A CCSDS demuxer, taking input from a VCID and extracting a stream of CCSDS frames
  • A simple derandomizer, taking randomized CADUs and doing the work

This is very much a work-in-progress, so some abstraction (eg, for different frame sizes, VCID encryption marker parsing, etc) is not yet implemented as well as all the planned modularity features.

Building

This project uses CMake, so all you need to do is those commands :

mkdir build && cd build
cmake ..
sudo make install
