| Summary: Track earth satellite TLE orbits using up-to-date 2010 version of SGP4 | |
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. 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.

* Fri Dec 08 2023 Dirk Müller <dmueller@suse.com>
- update to 2.23:
* Tweaked tests to resolve breakage introduced by Python 3.12.
* Wed May 31 2023 Dirk Müller <dmueller@suse.com>
- 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.
* Sun Jul 04 2021 Ben Greiner <code@bnavigator.de>
- Update to version 2.20
* Taught sgp4init() to round both epochdays and jdsatepochF to
the same 8 decimal places used for the date fraction in a TLE,
if the user-supplied epoch itself has 8 or fewer digits behind
the decimal point. This should make it easier to build
satellites that round-trip to TLE format with perfect accuracy.
* Fixed how export_tle() formats the BSTAR field when its value,
if written in scientific notation, has a positive exponent.
* Fixed the epochyr assigned by sgp4init() so years before 2000
have two digits instead of three (for example, so that 1980
produces an epochyr of 80 instead of 980).
- Release 2.19
* Extended the documentation on the Python Package Index and in
the module docstring so it lists every Satrec attribute that
this library exposes; even the more obscure ones might be
useful to folks working to analyze satellite orbits.
- Release 2.18
* If a TLE satellite number lacks the required 5 digits,
twoline2rv() now gives the underlying C++ library a little
help so it can still parse the classification and
international designator correctly.
* The Satrec attributes jdsatepoch, jdsatepochF, epochyr, and
epochdays are now writeable, so users can adjust their values
manually — which should make up for the fact that the sgp4init
() method can’t set them with full floating point precision.
- Release 2.17
* Fixed where in the output array the sgp4_array() method writes
NaN values when an SGP4 propagation fails.
* Wed Feb 17 2021 Ben Greiner <code@bnavigator.de>
- 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)
* Sat Jan 02 2021 Benjamin Greiner <code@bnavigator.de>
- Update to Version 2.14
* New data formats: added OMM message support for both XML and
CSV, and added support for the new Alpha-5 extension to TLE
files.
- Drop sgp4-fix69-precision.patch merged upstream
* Fri Oct 16 2020 Benjamin Greiner <code@bnavigator.de>
- Apply upstreams sgp4-fix69-precision.patch instead of own fix
gh#brandon-rhodes/python-sgp4#69
* Fri Oct 16 2020 Benjamin Greiner <code@bnavigator.de>
- Update to version 2.13
* Enhanced sgp4init() with custom code that also sets the
epochdays and epochyr satellite attributes.
* Fri Jul 10 2020 Benjamin Greiner <code@bnavigator.de>
- yank Python 2 package
* Thu Jul 09 2020 Benjamin Greiner <code@bnavigator.de>
- initial package with version 2.12
