Sextants assisted in determining a plane's location while in-flight by using the heavenly stars' positions.
According to the National Museum of American History, Smithsonian Institution:
The Link A-12 sextant was designed with the assistance of Philip Van Horn Weems just prior to World War II and made by Link Aviation Devices, which produced the Link Trainer.
The A-12 sexent represented a new generation of “averaging” sextants that compensated for “Dutch roll” in airplanes by taking multiple sightings and computing an average without manual calculations.
