# From strings
tle = read_tle(tle_string)
tle = read_tle(line1, line2; name="ISS")
tles = read_tles(multi_tle_string)
tles = read_tles_from_file("tles.txt")

# Without checksum verification
tle = tle_nc"..."

Fetching from CelesTrak

fetcher = create_tle_fetcher(CelestrakTleFetcher)
tles = fetch_tles(fetcher; satellite_name="ISS")
tles = fetch_tles(fetcher; satellite_number=25544)
tles = fetch_tles(fetcher; international_designator="98067A")

TLE Fields

Field	Unit	Description
`inclination`	degrees	Orbital inclination
`raan`	degrees	Right ascension of ascending node
`eccentricity`	--	Orbital eccentricity
`argument_of_perigee`	degrees	Argument of perigee
`mean_anomaly`	degrees	Mean anomaly
`mean_motion`	rev/day	Mean motion
`bstar`	1/Earth radii	BSTAR drag term
`epoch_year`, `epoch_day`	--	Epoch

Utilities

jd = tle_epoch(tle)                    # Julian Day of epoch
dt = tle_epoch(DateTime, tle)          # DateTime of epoch
str = convert(String, tle)             # Back to TLE string format
chk = tle_line_checksum(line)          # Compute line checksum

Key Conventions

TLE angles in degrees (TLE standard), mean motion in rev/day
Search precedence: satellite_number > international_designator > satellite_name
@kwdef constructor: required fields are epoch_year, epoch_day, inclination, raan, eccentricity, argument_of_perigee, mean_anomaly, mean_motion
