#pysattracker

Python library for calculating azimuth, elevation, doppler shift etc for satellite overflights.

#dependencies sudo pip install pyephem

#install There is no special library installation available. Just clone it into your project directory.

git clone https://github.com/cubehub/pysattracker.git

Or it is better to use it as a submodule if your project is already using git for version control.

git submodule add https://github.com/cubehub/pysattracker.git

#example

import sys
import time

from pysattracker import sattracker
