Hi folks,
Only loosely related to my question just posted, I'm interested to know
more about a primative navigation method I've read of. The idea is that
if one projects an imaginary line through the cusps of a crescent moon
down to the horizon, that gives the approximate position of South (or
perhaps North depending on your hemisphere).
How accurate is this position compared to true south? I'm guessing it
depends on the time of year, phase of moon and latitude - can any one
supply formulae? Working it out from first principles is beyond my math
ability.
I'm thinking that if I can use the moon to find south, I can then
measure the azimuth of the sun and use that to get time of day...
Thanks,
Steve
