I imagine one could make a modern device that tracks position by watching the sky. I wonder how well could that work in bad weather. Is there any light spectrum of the stars that passes through a serious storm? Humans may be incapable of seeing it but how about advanced telescope/camera?
- dbenjamin 9y agoThis has existed for quite a while. The SR-71 (introduced in 1966) had an astro-inertial navigation system that tracked stars to reduce error in a standard INS. Using spectrum filters, was able to track stars day and night (and I imagine potentially in bad weather). https://timeandnavigation.si.edu/multimedia-asset/nortronics-nas-14v2-astroinertial-navigation-system https://timeandnavigation.si.edu/multimedia-asset/nortronics...
