I know the usa is working on optical and electronic technology to use the stars even during the day. They can combine that with inertial guidance on cloudy days

- sn_master 5y agoYeah, because SR-71 was very fast, they had to build special computerized star-based navigation system for it, as this was the early 1960s, a decade before GPS. I wonder how similar the new and old systems are. All the principal astronomical science hasn't changed much at all, we just got faster compute and better optics. https://timeandnavigation.si.edu/multimedia-asset/nortronics-nas-14v2-astroinertial-navigation-system https://timeandnavigation.si.edu/multimedia-asset/nortronics...
- trhway 5y agothe star-based navigation was common on ICBM back then and i think still is.
