but there is still a delay up to 7 minutes. That's a long time for positioning on a longitude

I'm not sure what you mean by 7 min. delay. Please explain where it occurs.
Edit: Oh wait! Are you referring to my post #47 above? Well, I made a big mistake when I posted that. I was trying to use the Sun Almanac to find Latitude. BUT, what the SUN ALMANAC is for is locating your LONGITUDE. So if thats what you meant by 7 min....disregard that post.
Only two bodies come to mind when trying to obtain LATITUDE, those would be, POLARIS, and the, SUN at noon. Trying to get the other 56 navigational stars or moon at meridian passage would require additional pgms such as starrynight or starcalc. Meridian passage provides an east to west line of position (LOP) which intersects the computed vertical Longitude, giving us a fix....but, you know all that and I'm preaching to the choir

I'm afraid, we have to make our own table for every starting position.
Am I right or wrong?

Naw, you shouldn't have to...just use the above GMT conversion chart. It'll work for every location in the world.

Tnx for the mod, minimax.
