North Korea's missile tests may sometimes fail, but the program will continue to make progress in building bigger, more powerful missiles, according to new research presented at the meeting of the American Geophysical Union, Tuesday.
In April this year, the country launched a Taepodong-2 missiles with a view to placing the satellite in orbit. It does not seem to do, even though North Korean government says it does.
As a bullet flew up and over Japan, it punched holes in the ionosphere, the upper layer of Earth's atmosphere. With more than 1,000 GPS receivers in Japan, Kosuke Heki, a specialist in geodesy Hokkaido University, was able to calculate the trajectory of rockets at the sight of the interaction between the exhaust and charged ions of oxygen to part of the environment around the world.
While the results do not dispute the conclusion that the launch was a failure, the work provides some interesting data on the relatively enigmatic North Korean missile program. For one, Heki said the missiles get better Taepodong-1 launched 11 years ago, which are listed in the same dense network of GPS sensors.
On the first two rockets in the ionosphere, Taepodong-2 is eight times as many molecules of water in their customers.
"You may see an increase in the onslaught Taepodong series," wrote Heki get to your presentation.
The work was carried out during the field sensitivity GPS to reduce the electrons in the ionosphere. Water molecules introduced rocket consumers [pdf] becomes positively charged oxygen ions through the ionosphere. The H20 molecules then combine with free electrons, the depletion of the total number of electrons in place. This is the opening Heki same, and it is larger, more water is introduced, the larger rocket.
Geoff Forden, an expert in missile tracking and weapon systems at MIT, said the technology for tracking ballistic missiles is "very interesting" and possibly unprecedented. Thus, it is better than what the satellite that the government can not achieve.
"Their decisions are still very useful for analysts outside the U.S. government in determining the trajectory and missile capabilities and features, but there is no better than we can do in the infrared satellite to monitor rocket exhaust during its entire run trajectory," Forden wrote in an e - mail. "So their system is very exciting for us [non-governmental organization-] people, but it is important that the government in determining missile capabilities."
While stressing the importance of procedures for people outside of government, Forden also question how accurate GPS-array method could eventually be.
His own analysis of the missile flight, based on direct observation satellite image of the Contrail Rockets is an important proof that the North Korean missile would not even attempt to get space. Instead, it took a more horizontal trajectory, in line with a gun, not the starting point.
