Boeing's B-52 angle computer achieves 0.1° star-tracking precision in the Astro Tracker. Ken Shirriff details this 1960s electromechanical system on Righto.com (April 2024). It uses 19 components under a 4-inch glass dome. Boeing confirms its navigation role on the B-52 page.
Ten amplifier-computer units drive operations. Nine control panels input data. Three Star Data displays track three stars. The US Naval Observatory (USNO) provides Air Almanac data every 10 minutes.
Star Tracker Design in B-52 Angle Computer
Navigators enter USNO Air Almanac data into displays. Gears and cams compute angular differences between observed and cataloged stars. Shirriff's teardown explains these mechanical steps.
Photocell sensors detect starlight through dome filters. Mechanical linkages auto-center stars on mirrors.
Amplifiers boost photocell signals. Servos adjust dials for azimuth (0-360°) and altitude (0-90°). Boeing archives stress reliability over vacuum tubes for long flights.
The system cuts drift on 24-hour missions. Shirriff cites 1972 photos of four active panels mid-flight.
Precision Specs of B-52 Angle Computer
Micrometer-machined gears ensure 0.1° resolution. The dome scans horizon to zenith.
Cam profiles perform spherical trigonometry mechanically. Electromechanical relays switch paths reliably.
Crews calculate sidereal time from almanac tables. Boeing states this matches 1960s inertial systems.
Shirriff measures tolerances at modern levels. USNO almanacs deliver 0.01° data accuracy.
