"Monitoring system of day radical space " (the significant progress direction that SBSS) is construction of ability of perception of American space posture. SBSS system will form network of all-around dimensional target surveillance together with monitoring system of other space target, let aerospace target do not have place escape form. So, does the sense that dimensional posture feels where? Where are the characteristic of day radical space surveillance and advantage? Is the development state of affairs of each country how? See engage by special arrangement of daily of science and technology stalk of grain only please -- those who let aerospace target do not have place escape form " weather eye "
A few days ago, headquarters of air force aerospace alleges " monitoring system of day radical space " (the satellite of SBSS)10 unit already was had preliminary fight ability (IOC) , this indicates monitoring system is in a day radical actual combat ca 15 pin vga cable to hdmi pacity already was had inside cycle of its research and development. This satellite blasted off on September 25, 2010 by orbit science company enter the space, it is the first satellite of SBSS system. According to the plan, the SBSS system that will launch subsequently 20 unit are the constellation that comprises by 4 satellites, stronger than 10 unit functions, stability is better.
Long-term since, american army proposes the form of ability of dimensional posture perception the emphasis that plans as dimensional antagonism to develop way all the time. Dimensional posture feels a system to be in charge of getting dimensional information to monitor reconnoiter and environment monitor information, for defence sex and aggression sex space antagonism provides overall information support. As the addition of global spaceflight activity, issue of collision of dimensional fragment, space is increasingly outstanding, especially after incident of barge against of satellite of beautiful 2009 Russia, american army takes development space posture seriously to feel ability more.

Advantage of surveillance of target of day radical space is clear
Will tell from broad sense, dimensional object is the object that dimensional posture feels, if pass fragment of satellite of work of course of the strategic missile middle of aerospace, discretion, deserted satellite, space temporarily, and the planet of the asteroid that passes close ground space and comet, deep space and star. And will tell from narrow sense, surveillant and main application defies in the space and dimensional safety upholds dimensional goal on, because this day radical deep space explores a part to not be inside the limits that dimensional posture feels, but target of space of close on technical implementation ability ground monitors and day radical deep space explores the place that has a lot of likeness.
On Fe satin pjs for girls burary 4, 2011, american the Pentagon was announced " strategy of aerospace of American state security " , make clear in this strategy put forward: "We will increase our information capacity, strengthen forecast description of sexual perception, feature, early-warning and responsibility to return investigate, better the activity inside monitoring aerospace domain. Accordingly, aerospace posture perception and fundamental sex information will continue is the work that provides preferential sex most, because they are the ability that we retain understanding to be disturbed naturally, understand the crux of force of other behavior physical ability, activity and intent. " at the same time, the United States still feels aerospace ability to serve as leader and the important step that restrain other spaceflight country, "The United States is the leader that aerospace posture feels, can use its knowledge to promote collaboration to change aerospace to feel an impact, support safe space activity, safeguard the aerospace ability of the United States and allied country and activity. " accordingly, the United States increases dimensional posture to feel systematic compose to build ceaselessly, continueing to perfect, enhance monitoring system of foundation space target while, increased the construction of monitoring system of target of day radical space.
Through 50 old development, the United States built deploy in the whole world many ground are nodded, explore radar by many 30, dog radar, monitor into the foundation space that comprises like detector of radar, optical binoculars and signal of passive radio frequency net, can catalogue manage major space end. But as a whole, monitoring system of target of American foundation space still cannot satisfy perception of posture of U.S. Army space and requirement of dimensional opposed military affairs adequately. It is to still have cover blind area, 2 it is foundation observation equipment gets the impact of environment of weather, air is bigger, incidental observation error.
The development o the most popular 15 pin vga f monitoring system of target of day radical space offsetted these weakness effectively. In target of space of office of different course upside many surveillant satellite, satellite has monitoring system of target of system of group net, day radical and foundation space the measure such as photograph combination, reduce the observation blind area of pair of space targets effectively. Although monitoring system of target of day radical space accepts emissive restriction, cannot carry large observation equipment, but it is OK to go up because of in course close quarters observation is certain target spacecraft, consequently its observation precision did not drop. Contrary, because outer outer space does not have atmosphere keep out, the result that the visibility sex of optical sensor compares ground facilities is close friends relatively a few. Have the cause of fast track satellite of height of about 36 thousand kilometer so to earthly synchronism orbit especially, monitoring system of target of day radical space has better exploration effect tha 12 volt adaptor plug n ground system.
furniture lightThe function of monitoring system of target of day radical space and right reconnaissance satellite has the place of a lot of likeness, it is reconnaissance satellite has observation to interested target. Different is, the characteristic of the target of observation of place of monitoring system of target of day radical space, the form that gives day radical the syst the best selling satin pjs em is built bring more challenges. Ground target and the opposite geometry relationship to ground observation satellite are stabler, relative speed is lesser also. And satellite of surveillance of target of day radical space concerns relative to the geometry at dimensional target change is bigger, opposite rate is older also, can achieve 15 kilometers greatly most / second. How to undertake to the target below such high speed condition observation is mixed dog, it is monitoring system of prospective space target the crucial technology problem that the need in development solves.
American day base general situation of dimensional target monitoring system
Be in early 1996, the United States blasted off " satellite of middle space test " MSX. The main equipment that carries on MSX has: The space is infra-red into like binoculars (SPIRIT Ⅲ ) , ultraviolet with visible light camera (UVSI) is mixed sensor of day radical visible light (SBV) . The discovery that main task is pair of missile middles and dog, undertake missile middle early-warning. This project finished technical test and verify 1997, in beginning to blend in project and technology dimensional target monitoring system, move formally 1998, retreated be sent on a diplomatic mission to use 2008. MSX test and verify early-warning of new generation missile and defence place use detector technology, collect and statistic valuable setting and target data, its maturity technology will change new generation on monitoring system of target of day radical space.
SBSS project was started formally 2002, main purpose is to build constellation of satellite of remote sensing of optics of orbit of a low-lying ball, have stronger orbit observation capacity, repeat observation cycle short, and but round-the-clock observation, can increase the exploration capacity of object of American deep space substantially. According to saying, SBSS system will make the traceability of satellite of dormant to the earth orbit raises the United States 50% , at the most popular selling 15 pin vga same time American space target catalogues the newer cycle of information by present 5 days or so shorten, the dimensional situation that improves an U.S. Army greatly thereby feels ability. SBSS system development will divide a phase to undertake: The target of the first phase is development and deploy SBSS system the space that 10 unit satellites provide a kind to transfer is surveillant ability, object of orbit of surveillance close ground; Deploy of the 2nd level general defends astral constellation by what 4 SBSS satellite comprises, will use technology of more advanced global space surveillance. Predict 2015 SBSS system succeeds after deploy, the United States will form space surveillance of unifinication of heaven and earth.
Differ in the SBSS system of low course with deploy, air force is being developed and of deploy " orbit deep space is become like appearance " (ODSI) system is by move in the satellitic constellation that dormant orbital becomes the earth to be comprised like the satellite, its are main the task is to carry out dimensional target to identify, film the earth is dormant the high resolution image of orbit space target, and real time or fixed ground provide pertinent information, support perception of whole space battlefield and dimensional antagonism to fight. January 2005, 3 companies adopt Boeing, Luo Ma and Nuo standard the contract trade that contest mark makes ODSI concept consider, by the plan ODSI satellite will undertake emissive first 2015.

Eliminate afore-mentioned large days base beyond dimensional target monitoring system, air force develops tiny satellite actively still, let its make the main component that dimensional inspect eyesight measures. Tiny satellite cost cycle of low, development is short, can blast off in time in war or urgent hour, and comprise constellation or can be undertaken by many spacecraft form into columns, those who achieve pair of key goals is seasonable and accurate dog monitor. The program that tiny satellite uses in surveillance of space of U.S. Army future includes: One, in the light of the likelihood that appears suddenly inimical is not cooperative space target, when other day base, foundation space monitors detector cannot get place to need about the target when more detailed information, can use tiny satellite (include to be in course is resident and answer the tiny satellite that launch in time) near an end, get more detailed target feature data, conclude the intent that is not cooperative target. 2, be aimed at the cooperative space capital that needs special protection, can be near its deploy small satellite, surveillance suffers protective spacecraft surroundings, undertake early-warning to menace, judging this menace is to destroy factitious still attack naturally, take defence step effectively. The tiny satellite project that at present the United States may use at dimensional target to monitor basically has " near field evaluates defence natrium star independently " (ANGELS) plan, " dimensional test satellite " (XSS) plans and " small-sized orbit fragment is explored, capture with dog " (SODDAT) plan.
In addition, air force develops " the system outside Tian Jigong " (SBIRS) and " the space dogs with monitoring system " (although STSS) satellite is develops to realize missile defense system, but also have very strong day base capability of dimensional target surveillance.
Day of other each country base dimensional target monitoring system
Current, other country also begins to realize the value with surveillant target of day radical space, but with American much constellation, much a fair amount of confidence paragraph, the pattern that whole world of much task, unifinication 15 pin vga best buy enclothes is different, the development that they take tiny satellite, complex job according to their scientific research level and economic actual strength is politic, when developing other spaceflight project, be opposite actively the crucial technology related system of target of day radical space undertakes technical test and verify.
dog crates large"Sidereal small oscillatory observation " (the least outer space on the world that MOST) is Canadian development is telescopic, basically use at astronomical observation, but the clearance in astronomy task (the) when moving to just undertake software is updated maintenance mixing regularly namely, MOST still is used to undertake the dimensional target besides the task explores an experiment, undertake test and verify of technology of key of system of target of day radical space experiments. Current, canada is being developed " satellite of observation of course of on any account " (NEOSSat) project, also be astronomical observation project, this task expects to use an optical telescopic load, finish two kinds to observe the task in course: Surveillance of close ground space and fast track space are surveillant, discover and observe close ground asteroid and comet, decide its run orbit.
Use the technical fruit that scientific project gathers, canadian department of defense accelerated space surveillance (the research and development of CSSS) works, the dimensional surveillance that this system is Canada plans (the core part in SofS) . "Sapphire " the main component that the satellite is this system, it is one carries photoelectricity the moonlet of effective load, net of American space surveillance will be made after investment is used (the one part of SSN) . "Sapphire " fragment of the satellite that main observation target of the satellite is the activity in aerospace and invalidation satellite, space.
Germany predicts to blasted off 2013 " AsteroidFinder " satellite, it is a small moonlet with satellite of orbit of observation close ground and dimensional fragment. University of Italian Rome La Sapienza (call Rome again one big) GAUSS group is developing Unisat-5 satellite. This are tiny the satellite basically is used at civil science to experiment, use optical observation system to undertake monitoring to dimensional fragment.
See not hard, be in domain of observation of target of day radical space, the United States remains those who take advanced line to get bellwether. Can foreknow, after 2015, what plan when the United States is all after monitoring system of target of day radical space finishs deploy to realize actual combat ability, aerospace is peremptory became the United States hind garden, all every act in aerospace do not escape to give the United States these " weather e most popular selling satin pjs ye " surveillant, this will increase the security of aerospace and even earth greatly. However, this also the 12 volt adaptor price technical hegemony that certainly will brings about the United States and political hegemony get consolidating further, again each person that has deep love for peace is not willing to see this.
