2月27日的Nautical Calculator应用程序分析

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 - Utility other features can be enabled. - Calculate Average speed - E.T.A. calculation - Route plan, for manual waypoints planning - Waypoint route - Route mix with parallel limit - Rhumb Line Parallel/Meridian intersection - Follow on same Rhumb Line route - Opposite course rendez vous - Route correction - Calculate Amplitude at sunset and sunrise - Compass Error - Solves Drift problem - Solves Tides problem - Solves Tidal current problem - Solves Under keel clearance problem - Wind calculation with Beaufort classification - ABC Tables (azimuth, initial course, right ascension with unknow star) - Nautical almanac - Moon phases - Celestial Navigation with position line - Meridian transit - Celestial observation - Coastal navigation - Wheel Over - Draft Survey - Converter - Anchorage - Interpolation 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. follow on facebook https://www.facebook.com/NauticalCalculator
