Orbit Determination

The ephemeris OEM files are generated by fitting a subset of
USSPACECOM's Special Perturbation (SP) ephemerides.

We use our open-source orbdetpy library, which is based on Orekit.
The library is available at https://github.com/ut-astria/orbdetpy.

Visualization

Data obtained from the sources listed above are stored internally as
EME2000 state vectors. Orbits are visualized using the equations of
Keplerian motion. Perturbations from Earth oblateness, third bodies,
atmospheric drag, solar radiation pressure etc., are not taken into
account in order to reduce CPU cost.
