On November 28, japan uses H2A-16 name carrier rocket is successful will the name is " optical 3 " data gathering satellite sends book orbit. Japanese media says, the reconnaissance satellite that satellite of 3 data gathering launchs before than Japan wants optics advanced, its resolution has reached centimeter of level. Analytic personage points out, japan emphasizes development " high-end satellite " , hope to depend on commanding elevation of native and abundant aerospace of race to control of scientific research actual strength namely.
New satellite can discern car model
Japanese joint company will report on November 26, embarking Japan " optical 3 " the H2A rocket of data gathering satellite is in in the morning at 28 days deer center of universe of insular seed island blasts off enter the space. According to introducing, "Optical 3 " after the satellite is accepting the test of about 3 months, begin to enlist in army formally, replace blasted off in March 2003, design life to be 5 years " optical 1 " satellite. Japan " produce classics news " disclose 25 days, japan blasts off this " optical 3 " data gathering satellite will perfect Japan further " 4 celestial or heavenly body are " . According to saying, of Japan " information collect satellite " the system is comprised by 4 satellites, include radar satellite already, also include to take a picture satellite, can be opposite in order to ensure everyday inside global limits " appoint a place " film.
north face shirts" produce classics news " exposure, "Optical 3 " satellitic function is very advanced, operation sex is stronger also. "Optical 3 " the camera with the very advanced equipment on the satellite, can undertake filming continuously, to the identifying of ground object ability also promotes greatly. According to saying, "Optical 3 " the satellite uses black and white camera to film, its resolution can amount to 60 centimeters, and blast off before this " optical 1 " and " optical 2 " satellitic resolution is 1 meter only. "Optical 3 " satellite but the model of car of clear resolution ground, the goods that lades on the car repeatedly even also can look very clearly. Japan is in charge of the offi the best selling dearfoam slipper cial of satellitic data gathering expressing to media, "About ' optical 3 ' satellitic performance cannot say more, but the thing that cannot see in the past, can see now. " in addition, japanese official still discloses, future blasts off " optical 5 " function can rival the United States to be the same as model satellite, can arrive accurately by the face dot, identify a ground pedestrian.
Surveillant Korea and China
Make the goal of network of high accuracy satellite to Japan, " produce classics news " the analysis says, the nuclear installation of Korea and missile are the key monitoring target of Japanese satellite. "Optical 3 " the nucleus of instrument monitoring Korea that the satellite can depend on its high accuracy plans progress, stare at the every act of Korea missile closely. 1998, korea blasts off " hole of big river mouth " after a missile, japan uses Korea of reconnaissance satellite monitoring with respect to the decision. Nevertheless, 2003, carrier rocket launchs the H2A-6 most popular selling resealable bags name that carries two reconnaissance satellite failure, and " optical 1 " the satellite ever also appeared breakdown, this is protracted the step that Japan makes satellitic surveillance net. Blast off successfully this " optical 3 " satellite, the satellitic network of farther perfect Japan.
canon ef 15mmBesides monitoring Korea, china also may be one of targets of Japanese sat most popular selling hans wilhelm ellite. Be in early 2005, japanese media ever exploded makings, japanese satellite ever monitored China is in the oily gas field of the East China Sea. Japanese media discloses at that time, for the every act of cropland of oil gas of surveillant China the East China Sea, japan was expedited not the best selling hans wilhelm only patrol naval vessel and emissary machine, the dearfoam slipper size emissary satellite of Japanese defensive hall also monitors in rigor the development of cropland of oil gas of Chinese the East China Sea makes progress. At that time, japanese defensive hall and hall of maritime security personnel are the information that obtains through satellite of spy of beautiful during the day, affirmed oil field of Chinese spring dawn is mixed universal the oil pipeline between nature oil field already laid is finished. This shows, japan promotes the actual strength of reconnaissance satellite, basically be the East Asia related to Japanese interest " sensitive area " .
Develop high-end satellite technically
Current, japanese main put forth effort develops all sorts of high end satellites. 20 centuries since 80 t most popular selling dearfoam slipper ime metaphase, japan begins positive research and development satellite of advanced for military use, blasted off early or late " marine observation satellite - L, - Lb " , " satellite of Japanese world natural resources - 1 " and " satellite of advanced earth observation " the advanced satellite that waits for numerous model, had the capacity of reconnaissance satellite of production military affairs. In addition, a report June 2 points out Reuter, japan thinks Korea emissive missile and satellite are pair of Japan " potential menace " . Japanese premier holds the post of when the project team of a space below leader of Ma Shengtai man points out clearly, missile early-warning satellite has included Japanese space the plan, plan to perfect data gathering system of the satellite further.
Making high-powered emissary satellite actively, while exert oneself develops missile early-warning satellite, japan put forward even " want the sources of energy to aerospace " the most popular resealable bags tentative idea. The United States " natural " a report November 25 discloses magazine website, japanese scientist is collecting the satellite of solar energy in research and development, this kind of satellite can express solar energy those who send a world to receive a station. According to saying, this kind of solar energy collects a satellite not to suffer cloud layer and night effect. Researcher expects to built a full measure model 2030.
Link: Rely on commanding elevation of aerospace of advanced satellite race to control
Analytic personage points out, after realising in the satellite the domain cannot depend on the United States overly, japan resealable bags for food started plan of satellitic research and development in the round. Japan depends on his to wait for the advantage of science and technology of the domain in microelectronics, computer and new material, develop high-end satellite technically, the hope uses advanced satellite to promote Japanese space competition ability, open an international market further. In addition, h2 series carrier roc resealable bags ket of Japan is more mature, launch the satellite that is Japan provide reliable safeguard.
