Content

This repository contains a variety of independent tools and scripts. They are roughly ordered in this manner:

1. Up-/Downlink Degradation

   Artifacts used to correlate the Starlink network performance reported by Michel et al. to local weather data.

2. On-Board Compute Failure

   Data and tools to calculate the impact of radiation in LEO on compute hardware on-board satellites.

3. Orbital Maneuvers

   Tools to scrape and analyze public data on satellite maneuvers to calculate the impact of LEO satellite orbital maneuvers on the network.

4. Inter-Satellite Link Degradation

   Simulation and analysis tools to evaluate the impact of atmospheric refraction on inter-satellite links.

All directories contain their own README files with further information.
