Solar celestial position (as function of latt, long, time of day, date, )

  1. Feb 25, 2006 #1
    Hi, people!
    I'm looking for a way to predict the sun's (moon's) position in the sky at any given time/any given place. Equations would be great, maple worksheets aswell; links, estimates, tables, whatever.
    Would be used as (rough) backup for the backup of the navigation instruments during France -> Arctic Circle trek.
    Thx for reading; many thanx for any replies already :)

    Sincere apologies if this was already posted elsewhere (and I suspect it is), didn't have any luck digging it up...

    Some of these might give a basic start:

    Thanx, Labguy! I'm exploring all routes starting from what you gave me.
    Thing is, I'm going to need an offline solution; not easy to find :(

    Look into learning real celestial navigation. The new way to do it uses computer software (maybe on pda by now...) to replace the tables. Essentially, you just type in the time and position of several objects and it tells you your lat and long.

    The crude methods of prediction get really sloppy in the Arctic and Antarctic.

    HOLY ****
