ECSNorway Wrote:Navigation via star-sighting, and by improvised STL SPS, are standard components of the General Spaceman curriculum (Navigation 102) at Greenwood U.Navigation via Star-sihgting and other means are more precise, but not something that your random person in the street woudl be wiling to work on. The SPS may ony be precise withing a few kilometers,or even dozens/hundreds of kilometers far away from the inhabited zones, but it will be precise enough for normal use ("We want to go to Mars" "Turn twenty decrees left"). Before GPS, you needed to learn star navigation to cross the Atlantic ocean, but not to cross the English Channel or use a rowboat.
The General Spaceman curriculum would be for the profesionals pilots in cargo and passenger transports, military ships, astronomy/space hobbists and the like.
