Radar Plotting 與 VMGPolar 使用情況與統計

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.

VMGPolar

Sailing wind and boat speed calculator. Enter 3 values to calculate the rest, then save the data into a log that can be exported later. The input fields are highlighted, with the least intensive highlight marking the next field to become a calculated value when a new input is entered. BSP = Boat Speed TWS = True Wind Speed TWA = True Wind Angle AWS = Apparent Wind Speed AWA = Apparent Wind Angle VMG = Velocity Made Good (calculated only) Save and export data to build and validate polar graphs.
