- update to 2.22:
  * Added a ``satnum_str`` attribute, exposing the fact that the C++ now
    stores the satellite number as a string; and check that ``satnum`` is
    never greater than 339999.
  * Fixed the units of the ``nddot`` attribute when the value is loaded
    from an OMM record.  (Since the TLE computation itself ignores this
    attribute, this did not affect any satellite positions.)
  * Enhanced the fallback Python version of ``twoline2rv()`` to verify
    that TLE lines are ASCII, and added documentation using it to
    double-check TLEs that might suffer from non-ASCII characters.
  * If the user doesn’t set a satellite’s ``classification``, it now
    defaults to ``'U'`` for ‘unclassified’.
  * Added ``dump_satrec()`` to the ``sgp4.conveniences`` module.
  * Fixed the ``Satrec`` attribute ``.error``, which was previously
    building a nonsense integer from the wrong data in memory.
  * Removed ``.whichconst`` from Python ``Satrec``, to help users avoid
    writing code that will break when the C++ extension is available.

- Update to Version 2.16
  * Fixed ``days2mdhms()`` rounding to always match TLE epoch.
- Changes in Version 2.15
  * Fixed parsing of the ``satnum`` TLE field in the Python
    fallback code, when the field has a leading space
  * added OMM export routine.
- skip python36 (NEP 29, NumPy 1.20)

This Python package computes the position and velocity of an earth-orbiting
satellite, given the satellite’s TLE orbital elements from a source like
Celestrak. It implements the most recent version of SGP4, and is regularly run
against the SGP4 test suite to make sure that its satellite position predictions
agree to within 0.1 mm with the predictions of the standard distribution of the
algorithm. This error is far less than the 1–3 km/day by which satellites
themselves deviate from the ideal orbits described in TLE files.

If your platform supports it, this package compiles the verbatim source code
from the official C++ version of SGP4. You can call the routine directly, or
through an array API that loops over arrays of satellites and arrays of times
with machine code instead of Python. Otherwise, a slower but reliable Python
implementation of SGP4 is used instead.
