Astrosat is a Python package which calculates which satellites can be seen by a given observer in a given field of view at a given observation time and observation duration. This includes the geometry of the satellite and observer but also estimates the expected apparent brightness of the satellite to aid astronomers in assessing the impact on their observations.

Full documentation can be found here. A summary of installation and simple usage is given below.

Astrosat is available on the Python Package Index - PyPI and can be installed using:

pip install astrosat

Alternatively astrosat can be installed from source by cloning this project and running:

python setup.py install

Astrosat reads in an observation from a configuration file, then predicts any intersections between the observation and satellites using online tools. The easiest way to get started is to use the example files provided with this project. The example configuration file is params.yaml and an example script for generating a plot of the FOV of an observation with the satellite trails overlaid is given in tel_fov.py.
