Vector solution 2 CoP

Features Vector solution 2 CoP

Celestial navigation.Fix by two circles of position: vector solution.With a sextant take two altitudes, correct them and obtain the observed altitudes: Ho.Take the Nautical Almanac and find the coordinates of the celestial bodies: GHA, declination.Use this app to calculate the two solutions, and to plot the circles of position, or circumferences of equal altitude on Google maps.Running fix:- The app moves the first sight to the time of the second, taking into account the motion of the observer.Method explained in the papers:- Vector Solution for the intersection of two Circles of Equal Altitude.
