lisaorbits 2.2

LISA Orbits generates orbit files containing spacecraft positions and velocities, proper pseudo-ranges, and spacecraft proper times.

LISA Orbits

LISA Orbits is a Python package which generates orbit files compatible with LISA Instrument, LISA GW Response, the LDC Software, and LISANode. Among others, an orbit file contains the spacecraft state vectors, the light travel times and the proper pseudoranges.

Report an issue

We use the issue-tracking management system associated with the project provided by Gitlab. If you want to report a bug or request a feature, open an issue at https://gitlab.in2p3.fr/lisa-simulation/orbits/-/issues. You may also thumb-up or comment on existing issues.

Development environment

We strongly recommend to use Python virtual environments.

To setup the development environment, use the following commands:

git clone [e-mail]:lisa-simulation/orbits.git
cd orbits
python -m venv .
source ./bin/activate
python -m pip install --upgrade pip
python -m pip install -r requirements.txt
python -m pip install -e .

Workflow

The project's development workflow is based on the issue-tracking system provided by Gitlab, as well as peer-reviewed merge requests. This ensures high-quality standards.

Issues are solved by creating branches and opening merge requests. Only the assignee of the related issue and merge request can push commits on the branch. Once all the changes have been pushed, the "draft" specifier on the merge request is removed, and the merge request is assigned to a reviewer. He can push new changes to the branch, or request changes to the original author by re-assigning the merge request to them. When the merge request is accepted, the branch is merged onto master, deleted, and the associated issue is closed.

Pylint and unittest

We enforce PEP 8 (Style Guide for Python Code) with Pylint syntax checking, and correction of the code using the pytest testing framework. Both are implemented in the continuous integration system.

You can run them locally

pylint lisaorbits/*.py
python -m pytest

Use policy

There are currently no licenses associated with this project. However, we would like to foster open science in our community and share common tools. To this end, we are making LISA Orbits available for full members of the LISA Consortium to use in their research free of charge.

However, please keep in mind that developing and maintaining such a tool takes time and effort. Therefore, we would appreciate to be associated with you research.
