- Calculate point on WGS84 (solves 1st navigation problem)

- 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 and magnetic compass deviation

- Compass detections

- Solves Drift problem

- Solves Tides problem

- Solves Tidal current problem

- Wind calculation with Beaufort classification

- ABC Tables (azimuth, initial course, right ascension with unknow star)

- Nautical almanac

- Celestial Navigation with position line

- Meridian transit

- Celestial observation

- Coastal navigation

- Wheel Over

- Draft survey

- Converter

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.

The map, for size limit, will be show for scale over 60-70 Nm.

Jan 21 2015 | Version 1.2 Nautical Calculator Pro performs calculations and produces graphs of various problems of navigation The main functions are : DEAD RECKONING for Rhumb line and Great Circle Navigation, 1st problem: it helps navigator to determine his present position by projecting his past courses steered and speeds over ground from a known past position. He can also determine his future position by projecting an ordered course and speed of advance from a known present position. It does not allow for the effect of leeway, current, helmsman error, or gyro error. DEAD RECKONING for Rhumb line and Great Circle Navigation, 2nd problem: given the coordinates of departure and arrival, date of departure and speed, it calculates the routes and the distances of Rhumb lines and Great circles, the vertex coordinates, meridional parts, time spent in navigation and time of arrival. DEAD RECKONING for Rhumb line and Great Circle Navigation: Calculation of mixed Route : given the coordinates of departure and arrival and the parallel limit , calculate the coordinates of the two vertices the initial course and distance of the route with navigation mixed . This also shows a graphical representation . Reducing a celestial sight to obtain a line of position Compass Error By Azimuth Of The Sun at Sunrise and Sunset follow on facebook | |
