Custom ephemeris import

Import two-line TLE, named TLE sets or OMM JSON and validate identifiers, epochs and checksums.

TLE and OMM support

Import standard two-line TLE, named TLE collections or OMM JSON. Before saving, check NORAD ID, epoch, line length and checksum, and resolve duplicate identifiers explicitly.

Keep orbital data fresh

Long-range predictions drift as orbital data ages. Refresh data and verify the target identifier before important tasks.
