Celestial navigation - Astronavigation
Sight reduction:
- Marcq Saint Hilaire Line of Position, intercept method (p=Ho-Hc, Zn)
- Input for observed altitude Ho or instrumental Hs (Nautical Almanac data needed for the Sun and the Moon)
- Calculator: altitude Hc and azimuth Zn
- Running fix
- Plots up to 3 Marcq Saint Hilaire Lines of Position on Google maps
- Local hour angle (LHA)
Sight reduction is the process of deriving from a sight the information needed for establishing a line of position.
This app is a calculator to get the intercept from the assumed position of the observer AP(latitude, longitude), the geographical position of the celestial body observed, GP(Dec, GHA), and its corrected altitude Ho.
