Description

Celestial navigation - Astronavigation Sight reduction: - MarcqSaint Hilaire Line of Position, intercept method (p=Ho-Hc, Zn) -Input for observed altitude Ho or instrumental Hs (Nautical Almanacdata needed for the Sun and the Moon) - Calculator: altitude Hc andazimuth Zn - Running fix - Plots up to 3 Marcq Saint Hilaire Linesof Position on Google maps - Local hour angle (LHA) Sight reductionis the process of deriving from a sight the information needed forestablishing a line of position. This app is a calculator to getthe intercept from the assumed position of the observerAP(latitude, longitude), the geographical position of the celestialbody observed, GP(Dec, GHA), and its corrected altitude Ho. Manualand examples in the developer's website. Ref:https://en.wikipedia.org/wiki/Sight_reduction User interface: -Zoom buttons +/- - Map types: standard, terrain, and satellite -GPS location. ("Location" App permission must be allowed. Switch onyou GPS, and then automatic location detection is possible)
