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

ec1_tle = {
        "name": "ESTCUBE 1",
        "tle1": "1 39161U 13021C   24194.14473294  .00002706  00000+0  39461-3 0  9991",

    }

tallinn = ("59.4000", "24.8170", "0")

tracker = sattracker.Tracker(satellite=ec1_tle, groundstation=tallinn)

while 1:
    tracker.set_epoch(time.time())
