The "Astria OD/LeoLabs Data" source shows the results of orbit determination on radar data from LeoLabs. 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
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.
