Main requirements:

• Awaiting release of astropy 1.0.5

dev requirements:

• Awaiting release of Plumbum 1.6.0
• pytest 2.7.3

• Use pytest.approx
• Update documentation (I think just the py.test -> pytest change?)

Should use dev-requirements.txt instead, with -e .[test].

This is probably down to compiling numpy. I see from numpy/numpy#5479 that the builds shouldn't really be used.

We should probably download wheels from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy, perhaps placing into a numpy-wheels repository which the appveyor build can check out.

Currently, G × *_MASS is used, leading to false precision.

These should be added to the constants module.

The astrodynamics.constants module will contain constants from the IAU 2009/2012 System of Astronomical Constants (PDF).

Initially I had planned for these to be instances of astropy.units.quantity.Quantity, as I had started to do with astrodynamics.constants.wgs84.

I think that the astropy.constants.Constant class should be used, allowing source and uncertainty information to be captured.

I'm not sure the best way to do this. The autodata directive includes the docstring from astropy.units.Quantity, which we don't want.

I'd like some automated solution, perhaps a helper script is the best idea for now.

I found this project with same bug: hoechenberger/pphelper#41

It can work, because pyca/cryptography have it working.

• Linux (Travis)
• OS X (Travis)
• Windows (AppVeyor)

Since documentation is automatically built on readthedocs, building should be tested.

I'm attempting to install and test the python astrodynamics software on a Mac Pro running Mac OS X (ver. 10.12.1) Sierra under Python 2.7.12 in the Anaconda distribution.

I cloned astrodynamics from GitHub and installed the software from its high level directory using the command, python setup.py install. The installation appeared successful, but when I executed the command, conda list, astrodynamics failed appear. See the file conda_list.txt attached to this file. What is going on here?

When I run the tests using the command, python runtests.py, I got file mismatch errors as indicated in the file instellation and test of astrodynamics.txt. My question here is how does one fix this problem?

Please advise.

Sam Dupree.
