Reading TLE's
#############

The `Orbit` class is used to simulate the orbits of satellites.
It relies on `orekit` to simulate the position of satellites based on Two Line Elements (TLE) and on a linear interpolation to obtain a sufficiently fine time resolution while keeping compute time low enough.

A basic use of this class is as follows:

.. code-block:: python3

    from orbitx import TLE
    import numpy as np

    tle = TLE.from_sat_shortname(
        "S6", np.datetime64("2020-02-01T00:00:00"), np.datetime64("2020-02-01T12:00:00")
    )
    print(tle)

.. code-block:: text
