An Algorithm for Affordable Vision-Based GNSS-Denied Strapdown Celestial Navigation
1. IntroductionCelestial navigation is among the oldest forms of navigation in aviation [1]. The abundance of salient stars, known to high levels of precision, make them a useful cue for navigators when operating in clear conditions. The elevation of a star above the horizon would be measured, yielding a ‘line of position’. This process was repeated with different stars to fully determine the navigator’s position. The advancement of imaging and computing hardware saw the integration of autonomou...
