The electromechanical angle computer inside the B-52 bomber's star tracker
Summary
The article explains the B-52 Astro Compass Angle Computer, an electromechanical system that converts star positions into azimuth and altitude to support celestial navigation. It describes the Astro Tracker, Master Control interface, and the mechanical-numeric method of solving the navigational triangle, with notes and references. It places the device in historical context as an example of early automation that combined mechanical and electrical engineering.
