In this episode, we explore how satellite-based ADS-B technology is fundamentally changing aviation by achieving 100% continuous global air traffic surveillance. For decades, tracking was limited by the line-of-sight principle, where mountains, the Earth's curvature, and vast oceans restricted ground-based receivers to a range of only 100 to 150 nautical miles. These limitations created dangerous "dark zones" and "tracking gaps" where aircraft could essentially disappear from live view.
We dive into the mechanics of the solution: nano-satellite constellations equipped with receivers that capture "ADS-B Out" signals from space, bypassing all terrestrial obstacles. This data is relayed and processed in milliseconds, allowing operators to distinguish between live "SAT-ADSB" data and "ESTIMATED" tracking—a crucial distinction for maintaining safety in remote regions. Using live examples like Flight UX198 near the Azores and QF8 over the Pacific, we illustrate how the system provides a "more complete picture" by integrating satellite data with existing ground networks, MLAT, FAA ASDI, and Oceanic Reports.
Finally, the episode covers the practical impact for the industry. This "turnkey solution" requires no special equipment other than a standard transponder, making it easy for pilots and operators to comply with mandatory FAA, ICAO, and EASA flight tracking requirements. We also discuss how tools like the "My Fleet" dashboard allow for instant monitoring, ensuring that any loss of signal—whether due to a coverage gap or a deactivated transponder—is identified immediately to trigger emergency protocols.
