"North Korea Missile Test Visualization" which can grasp three-dimensionally the itinerary of the missile launching experiment carried out by North Korea

North Korea repeats missile launch experiments in a way that ignores protest voices from all over the world, international tensions are increasing, mainly in Japan, the United States, South Korea, China, Russia and others. Doing "nagix" with GitHubAkihiko Kusanagi'S publicly available "North Korea Missile Test Visualization"It is possible to grasp three-dimensionally the flight trajectory of the missile launched by North Korea or the launch test of" rocket ".

This site is published by the nonprofit organization "Nuclear Threat Initiative" (NTI)Database of missile launch tests by North KoreaIt can be confirmed the data of 116 launch tests that have been carried out since 1984.

When you visited the site, a page that stretches like a line of light from North Korea was displayed on a map centered on Japan's ocean. Of course, these lines show the locus where the missiles flew.


The map is rendered in 3D, it can be rotated like a globe to change the angle, enlarge or reduce the size. You can rotate the earth by dragging with the mouse, and dragging with the mouse while holding down the Shift key allows you to move the earth in parallel up and down and to the left and right instead of turning.


By making full use of this operation method, it becomes possible to check the locus of the missile including the altitude like this.


By turning on / off the check box at the name on the right side of the screen, you can switch the display of the locus. "HWASONG-12" chosen on the screen is "Mars 12" that landed in the Pacific Ocean across Japan over twice.


By clicking the trajectory, you can see detailed data and commentary about the experiment. In the first launch test of Mars 12 conducted on May 14, 2017, you can see that the launch was carried out in "Lofted orbit" with an altitude of 2111.5 km and a flight distance of 787 km.


Switching the check to "HWASONG - 14" will show the state of launch on Martian 14 super - lofted orbit. In the launch on July 28, 2017, it was reported in news etc. that the altitude had reached 3724.9 km, but you can see that in fact it was up to the highest altitude. In addition, the displayed trajectory is based on prediction to the last, it seems that it is not necessarily accurate.


There is a slider to select the Christian calendar at the bottom of the screen, and by switching it is possible to confirm the launch performed in that year. Also, on the left side of the screen, the name and number of missiles launched in that year will be displayed as a success / failure graph.


Even in 2009, a flying object crossing over Japan is firing. It is equipped with communication satellitesKwon Myeong 2Was launched and was launched under the name "rocket", not a missile. Although North Korea insists that the launch is successful, North America Aerospace Defense Command (NORAD)
I failed to put satellites into orbitI am watching it.


North Korea's first missile launch test is based on the Scud B missile implemented in 1984. Although the flight distance is unknown, the altitude is considered to have risen to 200 km.
