UAT versus One-Zero-Nine-Zero Extended Squitter, the Two-Frequency ADS-B Split, and the Traffic Picture Gap Every General Aviation Pilot Is Flying With

The FAA's ADS-B system runs on two incompatible frequencies - UAT and 1090ES - creating real traffic display gaps every GA pilot should understand.

GPS Spoofing, the Ghost Aircraft Appearing on ADS-B Displays Over the Eastern Mediterranean, and the Authentication Gap Nobody Built Into the System from the Start

GPS spoofing in the Eastern Mediterranean is generating ghost aircraft on ADS-B displays and triggering false terrain alerts on airliners - and the authentication fix was deferred decades ago.

GPS Jamming Over Active Conflict Zones, the ADS-B Surveillance Picture You Cannot Trust, and the Navigation Assumption Nobody Stress-Tested Before It Started Breaking

GPS spoofing over active conflict zones is corrupting the ADS-B position data controllers rely on for separation, with over 2,000 interference events logged in a single week in early 2024.

The FAA LADD Program, the Gulfstreams That Vanish from Public Tracking While Still Broadcasting, and the Safety Research Blind Spot Nobody Wanted to Admit

The FAA's LADD program lets private aircraft disappear from public tracking apps while still broadcasting ADS-B - and the safety research tradeoff is rarely discussed.

GPS Spoofing, Phantom Positions, and the Structural Vulnerability at the Core of ADS-B That the Aviation World Is Still Racing to Fix

GPS spoofing corrupts ADS-B position data silently, placing phantom aircraft on ATC scopes while flight crews remain unaware - a structural flaw at the heart of modern aviation surveillance.
