Inside the B-52’s 1960s electromechanical star tracker that automated celestial navigation before GPS
EDITOR BRIEF
The article explains how the B-52 bomber used an automated Astro Compass system to navigate by stars before GPS existed. Its Angle Computer used electromechanical analog computing to model the celestial sphere and convert star positions into navigation angles for the aircraft.
INSIGHTS
The system shows how Cold War-era engineers solved complex real-time navigation problems without digital processors or satellite infrastructure. Its resilience highlights why celestial navigation remains relevant as militaries revisit non-GPS options in an era of jamming and spoofing risks.
