Ep 67 - The Ionosphere Is Not a Lifetime Movie - Point One Navigation
Point One is hosting FUSE, a localization conference, on November 19 in San Francisco. Register at fuse.pointonenav.com with code POLYMATH This week, Ilia and Stefan sit down with Aaron Nathan, CEO of Point One Navigation, to ask why your phone knows which street you’re on but can’t find the door handle of the burrito joint. First, the game: RTK GPS meets prescribed burns. The result is a balloon fleet that spots fires, a drone fleet that sets them, and centimeter accuracy for the napalm. Along the way we cover the coastline paradox, “Mega Idaho,” and why mileage reimbursement is the real business case for precision. Then the real conversation. Aaron explains how RTK works, why the ionosphere is the main villain of satellite navigation, and why a forest fire barely registers (fireworks neither). We get into why Point One owns over 4,000 base stations rather than borrowing anyone’s, and what it’s like pitching investors on 4,000 one-meter property leases. We also cover jamming and spoofing, why the most safety-critical GPS receivers are the oldest and easiest to fool, and what it takes to beam corrections from a geostationary satellite at 4.8 kilobits per second. Ilia then argues that the only defensible data center in space is a small one, and gets fact-checked on the ISS’s power output live on air. Finally, a decade of building a robotics-adjacent company: surviving COVID and the chip shortage, resisting shiny objects, being “the adults in the room,” and why the unbundling of autonomy means the next robot company won’t need 30 billion dollars.
