WMM 2020 vs Radar Plotting Usage & Stats

WMM 2020

WMM 2020 is targeted towards anyone interested in navigation. This includes, pilots of aircraft, captains of sea going vessels, cartographers, engineers and surveyors. Anyone who uses maps and a compass will find the declination calculation (also referred to magnetic variation) very useful. (Declination is the difference between true and magnetic north and used when plotting a course on a map.) WMM 2020 (World Magnetic Model) calculates the magnetic flux density for any location on the Earth. The model is accurate for dates ranging from January 1, 2020 up through December 31, 2024. Using the model, the app calculates declination and inclination. In addition, the declination trend is calculated over the five year period.

Radar Plotting

This application solve this marine radar plotting problems: - Determine kinematic data of a target like CPA (Closest point of approach) and TCPA (Time of CPA) - Determine evasive maneuver by turn to starboard, left and speed reduction with single target. - Determine the current. - Determine maneuver to escape. - Determine maneuver to escape from faster ship. - Determine rescue maneuver. - Determine evasive maneuver by turning to the right and to left with two targets. - Calculate the detections by analyzing own ship and target positions In addition to the analytical resolution is a graphics representation on the radar sheet, with scale speed and adjustable distance in manual or automatic mode. Also in the graph it is selectable the representation of the true motion or relative motion.
