Collection of Python tools for working with CCSDS Space Packets

SPaC-Kit

✨ Introduction

SpaC-Kit is a collection of Python tools for working with CCSDS Space Packet. It can generically:

• Parse data files into Pandas DataFrames or Excel spreadsheets
• (Scheduled Feb 2026) – Generate documentation in multiple formats (HTML, Markdown, reStructuredText, PDF)
• (Scheduled Apr 2026) – Generate simulated packets

SpaC-Kit supports mission or instrument-specific CCSDS packet structures via plugin packages built on the CCSDSPy library.

[!IMPORTANT] This library is currently in active development.

Some functions are placeholders and may not yet have full implementations. Expect ongoing updates and new features as the library evolves.

🔌 Available Plugins

• Europa Clipper CCSDS packet definitions
• Want to define your own CCSDS packets? Open a ticket to start the discussion.

Acknowledgments

The work being done here heavily relies on the CCSDSpy library. It has been started as part of the NASA Europa Clipper mission Science Data System development and it is being now funded by a NASA ROSES grant.

Users

Requirement

Tested with python 3.13.

Optionnally, but recommended, create a virtual environment:

python3 -m venv my_virtual_env
source my_virtual_env/bin/activate

Install

Install you plugin library first, for example Europa-Clipper CCSDS packets definitions:

git clone https://github.com/joshgarde/europa-cliper-ccsds-plugin.git
cd europa-cliper-ccsds-plugin
pip install .

Install the SPaC-Kit package:

pip install spac-kit

Use

spac-parse --file {your ccsds file}

See more options with:

spac-parse --help

Developers

Requirements

Python 3.13

Create a virtual environment

For example in command line:

python3 -m venv venv
source venv/bin/activate

Install the latest development version of CCSDSPy (optionnal)

To install the latest version of CCSDSPy:

pip install git+https://github.com/CCSDSPy/ccsdspy.git

Deploy the project, for developers

Clone the repository

Install the package

pip install -e '.[dev]'
pre-commit install && pre-commit install -t pre-push

Run an example:

python src/spa_kit/parse/downlink_to_excel.py

or

spac-parse --help

or

spac-parse --file ./data/ecm_mag_testcase6_cmds_split_out.log --bdsem --header

Build and publish the package

Update the version number in file setup.cfg

Create a tag in the repository

Build the project:

python3 -m pip install --upgrade build
rm -rf dist/
python3 -m build

Publish the project:

twine upload dist/*

Acknowledgment

This package heavily relies on ccsdspy library (see https://github.com/CCSDSPy/ccsdspy).
