Nautical Calculator




    Nautical Calculator is an Android application that calculates rhumb line and great circle navigation.
    The application is totally free.
    The main functions are:
    - Given two coordinates, great circle and rhumb line courses, distances, great circle vertex and meridional parts is calculated, is show graphics.
    - Given a position, new position is determined by advancing it for courses and distances.
    - Wheel Over calculation
    - Compass detections
    - Draft survey
    - Converter

    other features can be enabled.

    - Meridian transit
    - Celestial observation
    - Coastal navigation

    In routes feature there is a world map: it isn't a nautical chart and is not for use as a saling chart, but as a simple general means of showing the courses through the water on earth, this map isn't for navigational purposes.
    No need connection for show the map; the map will be downloaded only one time.
