| We've discussed that method before and it's lesser accuracy but any additional navigational information that you have is useful. I think it is interesting that this method is at the heart of GPS, without it each of our GPS enabled devices would require an expensive atomic clock. The GPS in your phone, wristwatch, etc. has only a relatively inaccurate, cheap, clock and the GPS adjusts the presumed time from that clock to get the LOPs from each satellite to intersect at a point just like adjusting the time to get the moon LOP to cross through the star fix. When it does, you know the time is correct. gl --- On Tue, 12/18/12, Frank Reed <FrankReed@HistoricalAtlas.com> wrote:
