    Re: Can I Navigate Without an Assumed Position?
    From: Herman Dekker

    I wanted to know about where it was, and asked Starpilot TI-89 for one answer.
    Problem it needs a DR and it calculates automatic the refraction, but I gave it a try.
    DR 0°, 0°. Entered the 3 stars problem  that gives a few positions possibilities. I have taken
    arbitrary the last one, entered that as new DR and started over.
    This resulted in pos: 48° 34.4'N, 122° 15,3'W.
    Wel far from perfect.  But there in the neigborhood you are.
    One problem, the automatic refraction correction wil disturb the result, but it
    gives a rough idea.

    regards
