A detailed analysis of the B-52 bomber's electromechanical angle computer, an analog device that performed celestial navigation calculations before GPS. The system used physical modeling of the celestial sphere to track stars and compute precise headings accurate to 0.1 degrees. This electromechanical solution was necessary as digital computers weren't suitable for this application in the early 1960s.
Background
Before GPS, aircraft relied on celestial navigation using stars and planets for positioning. The B-52's Astro Compass system automated this process in the 1960s when digital computers weren't yet suitable for such calculations.
