T-Minus Space Daily

Signals Intelligence (SIGINT) is the practice of intercepting and analyzing electronic signals, like phone calls, emails, radar, and telemetry, to gather actionable intelligence for national security, defense, and military operations. It’s primarily conducted by agencies like NSA, but over the last decade many companies in the commercial sector have grown in this vital area of national defense, especially in space. Our guest is Dave DeWalt, CEO of NightDragon, who shared why his firm is investing in tech and space.

Zak Kassas, Professor in the Department of Electrical and Computer Engineering at The Ohio State University, recently released a white paper on “Navigating the Arctic Circle with Starlink and OneWeb LEO Satellites” and shares his insights. The study suggests that radio signals from low-Earth orbit (LEO) satellites could become reliable navigation alternatives, as disruptions to GPS services increase globally. Zak helps us understand how he reached that conclusion.
