LEOSatpy

LEOSatpy (Low Earth Orbit satellite python) is an end-to-end pipeline to process and analyse satellite trail observations from different telescopes.

Note

When publishing data processed and analysed with LEOSatpy, please cite LEOSatpy.

Two example of satellite observations reduced and analysed with LEOSatpy: V band observation of OneWeb-0108 taken with the 1.54-metre Danish telescope at the La Silla Observatory, Chile, and Sloan-r’ band observation of Starlink-5464 from the Ckoirama Observatory of the University of Antofagasta, Chile. Used comparison stars are marked with red circles. The position and path predicted by the TLE orbital elements are shown in blue.

The pipeline is written in Python 3 and provides the following functionalities:

Module	Function
reduceSatObs	Full reduction of raw-FITS images including bias, dark, and flat reduction.
calibrateSatObs	WCS calibration, i.e. plate solving, using GAIA DR3 positions, obtained via the Astroquery tool.
analyseSatObs	Satellite trail(s) detection and aperture photometry using comparison stars from the GSC v2.4.3 catalog.
