IoT Thrust Seminar | Counting Stars: Earth-based Strategies to Understand Space-based ISPs

Satellite communications is seeing a resurgence with new space-based ISPs such as Starlink. Using thousands of satellites in Low Earth Orbits, such megaconstellations of satellites aim to provide connectivity rivalling terrestrial broadband providers, and are largely succeeding. Yet, complexities created by the fast moving satellites may require reexamining or redesigning higher layers of the network stack. This talk will look at various ways to measure and understand the promise and pitfalls of space-based connectivity from right here on earth, using techniques ranging from browser extension-based measurements to developing a distributed testbed that aims to be a “planet lab for starlink” to developing a “digital twin” that can scale to the size of today’s megaconstellations and beyond.
