Something is wrong with my math.

Something is wrong with my math. The LOP aren't lining up correctly.

That's better, although now they all converge at the actual latitude but the dead reckoning longitude position.
-
Fixed the LHA computation to use the DR longitude instead of the actual longitude and now the lines of position converge very close to the actual location!

Intercept success! The Lines of Positions from two Sun sights converge on the actual location (within a few nautical miles at this scale)

Controversial opinion: navigation is much easier with decimal math instead of minutes and seconds. I make far fewer mistakes with base ten than sixty, plus 0.01 is slightly smaller than 1/60. And besides 1' equals 1 nautical mile only at the equator so it's not really very useful on the rest of the planet.

In Italy surveying operations are made with gradians: a right angle is 100 gradians.
