Title:
航跡描画装置、航跡描画方法、及びプログラム
Document Type and Number:
Japanese Patent JP6702598
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a flight trajectory plotting device, flight trajectory plotting method, and program that reduce costs required for construction of systems plotting trajectories of aircrafts, and can achieve improvement in accuracy of trajectories to be plotted.SOLUTION: A flight trajectory plotting device 100 is a device for plotting trajectories of aircrafts flying over set areas. The flight trajectory plotting device 100 comprises: an information acquisition unit 10 that acquires aircraft location information specifying passage points of aircrafts and passage time at which the aircraft passes through the passage point; a flight trajectory preparation unit 20 that specifies the passage point of each aircraft for each aircraft on the basis of the aircraft location information, connects between the passage points with a virtual line along a time sequence, and in this instance, when continuous three or more passage points are not present on a straight line, prepares the trajectory of the aircraft so that these passage points are located on a continuous virtual curve; and a flight trajectory plotting unit 30 that plots a part or all of the prepared trajectory on a screen.SELECTED DRAWING: Figure 1
