Come eliminare Circle Of Position Navigation

The app enables navigation with the sun and is comparable to satellite navigation on a chart plotter. A sextant is needed because, unlike satellites, the sun does not emit radio signals. The distance to an observer must therefore be measured manually with a sextant from the earth. For a position determination only the times and the sextant readings of two observations to be entered. The position is immediately displayed as a ship symbol on an electronic map. A track of the journey is displayed based on the positions determined and the data from an integrated dead reckoning module.
So, the app can be used by anyone without any knowledge of celestial navigation. The sun cannot be confused with any other star and is available all day. Navigating with stars requires specialist knowledge so that stars can be reliably identified. At night the height of stars cannot be measured because the horizon is not visible.

With this app it is now possible to have a real second independent navigation system on board that anyone can use immediately, even in stressful situations and without prior instruction. Celestial navigation is a demonstrably a valid and safe navigation method. Sailors should always be able to master and use classic celestial navigation.

A failure of satellite navigation is difficult to imagine, but not impossible. A lot of money is spent each year on buying and maintaining yacht safety equipment in case of rare incidents that normally do not happen, but very little is done or available in the event of satellite navigation failure.

This app makes it very easy to meet the requirements for navigational safety of the ship and crew. It is professional system and makes it possible to check the functionality of the on board satellite navigation electronics with a totally independent system. For some sailors, classic celestial navigation is even a passion, finding the way only with the help of the heavens. After all, sailing itself is a historical form of travel.

The app based on the ideas of the renowned German mathematician Carl Friedrich Gauss in 1809. His solution was way ahead of its time. A position is calculated from the heights of two celestial bodies, or the sun at two different times and entered on a nautical chart. Satellite navigation works similar way.
