Early failure of the Japanese space satellite radar imaging intelligence network may crash
Worried about a time when the crucial period to monitor DPRK collapse of space to create a separate intelligence network in East Asia is Japan’s space surveillance network has been a dream. Japan finally for the first time in 2007 by the two radar imaging satellites and two optical reconnaissance satellites to monitor the composition of the network, but the good times a month just to maintain. Japan’s “Yomiuri Shimbun,” August 28, Japan is the only way to penetrate the clouds and at night radar imaging reconnaissance satellite failure due to power failure , so that Japan’s “China to strengthen military and North Korea from developing nuclear weapons” to lose the most critical period important “Eye of Heaven”, the dilemma and even alarmed Japanese Prime Minister Naoto Kan. Failure of the radar imaging satellite earlier reports, the failure of the satellite was launched in February 2007, “Radar Satellite II.” Japan’s Cabinet Satellite Intelligence Center, said Aug. 23 they found that satellite failures, and to issue remote commands attempt to reboot the system. But the center, an official said the hope of repairing the satellite, “little.” Reported, the satellite design life is 5 years, in accordance with the plan should have been run until 2012. Preliminary determination of the center satellite early retirement because of the battery system failure. Reported that the satellite’s failure seriously affect Japan’s intelligence-gathering activities, “especially when North Korea tested a nuclear weapon, and China to strengthen military time.” According to the plan, Japan will launch the next fiscal year 2011, a radar imaging reconnaissance satellite, so the Japanese have to wait until fiscal year 2012 to once again formed by the two optical satellites and two radar satellites for reconnaissance satellite systems. Currently, in addition to Fengyun radar satellite, the Japanese and another three optical reconnaissance satellites in orbit, but a period of more than life. The Japanese government before the major US commercial satellite images using the information, but the United States to involve military security reasons to limit the image data, so their intelligence-gathering satellite Japan is very important for the sources of information . A senior official of Japan’s Defense Ministry described the “intelligence-gathering satellite surveillance through any type of activity to deter.” Naoto Kan on the 28th, said: “satellite intelligence gathering at night to play a significant role, failure is very regrettable. “He also stressed:” In order not to give adverse effects on intelligence gathering, to take all possible measures to save. “Japan Satellite Watch the road twists and turns in fact, the formation of Japan’s space reconnaissance systems, how the work has not been smooth. In 1998 North Korea launched ballistic missile over Japanese territory, Japan has launched satellites to monitor the network set up works. Under the original plan, Japan will be completed by the two synthetic aperture radar imaging reconnaissance satellite and two optical reconnaissance system consisting of space, they run in the 400 to 600 km high orbit, can be collected within 24 hours anywhere in the world image information. March 28, 2003, Japan will, “Optical Satellite I” and “radar satellite I” successfully put into orbit , Japan’s space reconnaissance CAPE made a good start, but good luck seems to end here. November 29, 2003, equipped with “optical satellite II” and “radar satellite II” reconnaissance of the H-2A rocket launch failures, satellite rocket all destroyed . Despite the successful launch since the two complementary, Japan finally finished two optical satellites and set up two radar reconnaissance satellites in orbit, the space surveillance network, but this situation is maintained for only a month. March 27, 2007, Japan’s Cabinet Satellite Intelligence Center, said long-term aging power system may lead to failure, “Radar Satellite I” in the year March 25 to stop working. Since then Japan has maintained that only one radar satellite in orbi
