New NAV system on the way
I have heard the Boffins are looking at a type of astral navigation similar to using a sextant but deriving position from many stars at once, totally passive and usable day night cloudy etc due to the system uses the detectable radiation from these stars
Could be all BS but the US had GPS for years before they allowed it for civillian use and GPS has been around for years ...
Could be the next big thing?
