Hi Paul. You wrote: "I'm new to navigation, and am doing some work on the usage of prime vertical sights. I know it gives longitude, but if you knew the time of sunrise, is it possible to obtain a value for lattitude too? " Welcome aboard. I'm not entirely sure what you're asking here. Are you saying that we've recorded the local time of sunrise? Perhaps at sunrise we look at a watch and note that the time is 0701 and later when we take the time sight the time is 0914. With that difference in time and the measured altitude for the time sight, you could presumably calculate the latitude. Is that what you have in mind? -FER --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to NavList@fer3.com To , send email to NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
