David Robinson - 2025 - A look at radio direction finding tools

Engineers explore architecture and security mechanisms for David Robinson - 2025 - A look at radio direction finding tools.

Summary

Aviation navigation basics

David Robinson surveys how aircraft and air traffic control determine position, from dead reckoning and legacy VOR/LORAN ground stations to modern GNSS (GPS, GLONASS, BeiDou, Galileo), inertial navigation, instrument landing systems, primary radar, multilateration, and ADS-B broadcasts.

GPS jamming and spoofing threats

He explains that state actors increasingly jam or spoof GNSS, forcing longer routes, higher fuel burn, and canceled Scandinavian flights. Flight-tracking sites map degraded ADS-B quality near conflict zones. Jamming floods weak satellite signals; spoofing transmits plausible but false time or position data.

Detection and historical stakes

Pilots may notice impossible position jumps or cockpit clock skew. Systems are beginning to alert crews. He cites Korean Air Flight 007's 1983 shootdown after INS drift into Soviet airspace as a catalyst for civilian GPS availability.
