Description
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. (Andrés Ruiz González. Journal of Navigation 2008, 61:355-365. The Royal Institute of Navigation).
- Use of rotation matrices to plot a circle of equal altitude. (Andrés Ruiz. JOURNAL OF MARITIME RESEARCH, Vol 8, Nº3, 2011)
Available on the author's website.
