Python coordinate conversions, following convention of several popular Matlab routines. Tested from Python 2.7 through Python 3.7+
For those not having AstroPy, lower accuracy fallback functions are included for some functions.
- prereqs
AstroPy, Numpy, Python 3 or Python 2.7
Development:
python -m pip install -e .
simple:
python -m pip install pymap3d
a few quick examples
import pymap3d as pm
lat,lon,alt = pm.eci2geodetic(eci, t)
az,el,range = pm.geodetic2aer(lat, lon, alt, 42, -82, 0)
Popular mapping toolbox functions ported to Python include:
aer2ecef aer2enu aer2geodetic aer2ned
ecef2aer ecef2enu ecef2enuv ecef2geodetic ecef2ned ecef2nedv ecef2eci
eci2ecef
enu2aer enu2ecef enu2ecefv enu2geodetic
geodetic2aer geodetic2ecef geodetic2enu geodetic2ned
ned2aer ned2ecef ned2ecefv ned2geodetic

- Atmospheric effects neglected in all functions not invoking AstroPy. Need to update code to add these input parameters (just start a GitHub Issue to request).
- Planetary perturbations and nutation etc. not fully considered.
