lumos.constellation.library.ConstellationFromTLE

class lumos.constellation.library.ConstellationFromTLE(tle_file_path)[source]

This class builds a constellation from a TLE file

Methods

`get_hcs_position`	Gets position of all satellites in constellation in HCS frame
`get_teme_position`	Gets positions of all satellites in TEME coordinate frame
`plot_hcs`	Plots satellite constellation in HCS coordinate frame
`plot_teme`	Plots satellite constellation in TEME coordinate frame

get_hcs_position(time, earth_location)

Gets position of all satellites in constellation in HCS frame

Parameters:

time (astropy.time.Time) – Time at which to get positions
earth_location (astropy.coordinates.EarthLocation) – Location at which to get positions in HCS frame

Returns:

altitudes (degrees), azimuths (degrees), heights (meters)

Return type:

tuple[np.ndarray]

get_teme_position(time)

Gets positions of all satellites in TEME coordinate frame

Parameters:: time (astropy.time.Time) – Time at which to get positions
Returns:: (x, y, z) position measured in meters
Return type:: tuple[np.ndarray]

plot_hcs(ax, time, location)

Plots satellite constellation in HCS coordinate frame

Parameters:

ax (matplotlib.pyplot.Axes) – Axis for plotting onto (must be polar projection)
time (astropy.time.Time) – Time at which to plot constellation
location (astropy.coordinates.EarthLocation) – Location on Earth at which to plot constellation

plot_teme(ax, time)

Plots satellite constellation in TEME coordinate frame

Parameters:
