CelestLab is a library of space flight dynamics functions.

This library has been developed and maintained by CNES (Centre National d’Etudes Spatiales, French Space Agency) for mission analysis purposes. It is used for trajectory analysis and orbit design for various missions.

CelestLab includes more than 200 functions that allow mission designers to perform various tasks such as: orbit propagation, attitude computation, elementary manoeuvre computation, change of coordinate systems, three body orbit analysis...

Selected examples from mission analysis typical studies are provided in the CelestLab help pages.
