Fetch satellite TLEs from various online sources

Project description

The python package satellitetle provides functions to fetch TLEs from various online sources (currently CelesTrak (SatNOGS), CalPoly and AMSAT) and allows using custom ones or Space-Track.org.

It was forked from the python package orbit.

Usage

Fetch TLEs for a single satellite from Celestrak:

from satellite_tle import fetch_tle_from_celestrak

norad_id_iss = 25544 # ISS (ZARYA)
print(fetch_tle_from_celestrak(norad_id_iss))

Fetch a large set of TLEs for a list of satllites from all available sources:

from satellite_tle import fetch_tles

norad_ids = [25544, # ISS (ZARYA)
             4298,  # QIKCOM-1
             40379] # GRIFEX

# Uses default sources
tles = fetch_tles(norad_ids)

for norad_id, (source, tle) in tles.items():
    print('{:5d} {:23s}: {:23s}'.format(norad_id, tle[0], source))

sources = [
    ('CalPoly','http://mstl.atl.calpoly.edu/~ops/keps/kepler.txt'),
    ('Celestrak (active)','https://www.celestrak.com/NORAD/elements/active.txt')
]

# Uses custom sources
tles = fetch_tles(norad_ids, sources=sources)

for norad_id, (source, tle) in tles.items():
    print('{:5d} {:23s}: {:23s}'.format(norad_id, tle[0], source))

spacetrack_config= {
    'identity': 'my_username',
    'password': 'my_secret_password'
}

# Uses default sources and Space-Track.org
tles = fetch_tles(norad_ids, spacetrack_config=spacetrack_config)

for norad_id, (source, tle) in tles.items():
    print('{:5d} {:23s}: {:23s}'.format(norad_id, tle[0], source))

# Uses only Space-Track.org
tles = fetch_tles(norad_ids, sources=[], spacetrack_config=spacetrack_config)

for norad_id, (source, tle) in tles.items():
    print('{:5d} {:23s}: {:23s}'.format(norad_id, tle[0], source))

# Uses custom sources and Space-Track.org
tles = fetch_tles(norad_ids, sources=sources, spacetrack_config=spacetrack_config)

for norad_id, (source, tle) in tles.items():
    print('{:5d} {:23s}: {:23s}'.format(norad_id, tle[0], source))

NOTE: fetch_tles downloads the TLE sets from all known sources, so it should only be used when fetching TLEs for a large set of satellites.
