satellite-dodging

To address the problem of bright commercial satellite streaks in images from the Vera C. Rubin Observatory, we create heuristics for satellite dodging strategies using the survey’s scheduling algorithm. We computationally forecast satellite trajectories to account for the growing satellite population during Rubin operations. Our results help maximize efficiency and quality of this flagship observatory.

Dependencies: As usual, suggest using anaconda and creating a fresh environement for installing with something like: conda create -n sat-env ; conda activate sat-env

• rubin_sim: Maybe just conda install -c conda-forge rubin_sim Full instructions at: https://github.com/lsst/rubin_sim
• shapely: conda install -c conda-forge shapely
• skyfield: pip install skyfield
