  • Calculating a lat long without a GPS

    We all use GPS, (Well most) and we all know what a Lat/Long is. But for the explorers of the past, working out a longitude was the biggest issue of the day, and it cost 1000s or ships and even more lives. A big enough problem the government of the time would give millions of dollars to the person who worked it out.

    In this video I attempt to explain simply, how they worked out longitude once they has a clock accurate enough to hold time. So bare with me... PS, Back to trip videos shortly.
