Celestial and DR Navigation   (details) 48 ENG   7 KB / 9 KB
ScreenshotTools for celestial navigation and dead reckoning. These programs were prepared primarily for the operator of a small ship (sailboat or powered yacht, with magnetic compass) not routinely using celestial navigation. Using these programs, one can take a round of sextant sights, and enter the necessary ephemeris data, without overlooking any necessary input.

Great Circle Navigation   (details) 48 ENG   6 KB / 9 KB
Helps do great circle navigation. Distances are in nautical miles. All programs provide a precision of better than 0.1'. If a vertex of the great circle is on the path traveled, provision is made for a "composite" (latitude limited) path, for example, to avoid icepacks or the Antarctic continent.
