Open Space Toolkit

The Open Space Toolkit (OSTk) is a collection of versatile libraries for aerospace engineering use, available in:

• C++ – the reference implementation, for portability and performance.
• Python – via C++ bindings, formidable for interactive use and prototyping.

Getting Started

Want to get started? This is the simplest and quickest way:

This will automatically start a JupyterLab environment in your web browser with Open Space Toolkit libraries and example notebooks ready to use. Nothing to download or install! 🚀

Local JupyterLab in Docker

Alternatively, you can run a pre-installed OSTk environment on your local machine. This process has the following requirements:

• Docker
• Git
• GNU Make

The following commands will start a JupyterLab server within a Docker container where the OSTk components are already installed:

# clone this repo
git clone https://github.com/open-space-collective/open-space-toolkit.git && cd open-space-toolkit

# Run the jupyter server inside of Docker
make run-jupyter

Once the container is running, access http://localhost:8888/lab and create a Python 3 Notebook.

Components

Name	Description	Version
Core	Fundamental types, containers and utilities.
I/O	Addressing, networking, database connectors.
Mathematics	Geometry, curve fitting, optimization.
Physics	Physical units, time, reference frames, environment modeling.
Astrodynamics	Orbit, attitude, access.

Using OSTk in your applications

To help jump-start using OSTk, here is a simple Docker image that you can use to create your applications.

Docker

ARG PYTHON_BASE_VERSION="3.11"

# Open Space Toolkit install image

FROM mcr.microsoft.com/vscode/devcontainers/python:${PYTHON_BASE_VERSION}

ARG OSTK_DATA_LOCAL_CACHE="/var/cache/open-space-toolkit-data"

## Install OSTk data install dependencies

RUN apt-get update && \
    apt-get install -y git-lfs && \
    rm -rf /var/lib/apt/lists/*

## Seed OSTk Data

ENV OSTK_PHYSICS_DATA_LOCAL_REPOSITORY="${OSTK_DATA_LOCAL_CACHE}/data"

RUN git clone \
    --branch=v1 \
    --single-branch \
    --depth=1 \
    https://github.com/open-space-collective/open-space-toolkit-data.git ${OSTK_DATA_LOCAL_CACHE} && \
    chmod -R g+w ${OSTK_DATA_LOCAL_CACHE}

## Update user id and group id with local ones

ARG USERNAME="vscode"
ARG USER_UID="1000"
ARG USER_GID=${USER_UID}
RUN sudo groupmod --gid ${USER_GID} ${USERNAME} && \
    sudo usermod --uid ${USER_UID} --gid ${USER_GID} ${USERNAME}

USER ${USERNAME}

## Install dependencies

COPY --chown=${USER_UID}:${USER_GID} pyproject.toml /home/${USERNAME}/tmp/

RUN cd /home/${USERNAME}/tmp/ && \
    pip --no-cache-dir install --user .[dev] && \
    rm -rf /home/${USERNAME}/tmp/

## Change default entrypoint to bin/zsh

ENTRYPOINT ["/bin/zsh"]

## Change default entrypoint folder to /app

WORKDIR /app

pyproject.toml

And an accompanying pyproject.toml file that should be in the same folder.

[project]
name = "my-app"
requires-python = ">=3.11"

dynamic = ["version"]

dependencies = [
    "open-space-toolkit-simulation~=X.Y.Z",
]

[project.optional-dependencies]
dev = [
    # Development libraries
    "ipython~=8.24",
]

Build and Run

You can then build the Docker image via:

docker build . -t my-app
docker run -it --rm my-app

Enjoy!
