The hd image was sent back by the aerospace science and technology group's gaojing no. 1 no. 03 and no. 04 stars. According to the description of the Taiwan media, "the downtown area of Taipei is very impressive.
Gaojing commercial remote sensing satellite system was developed by the general manager of the five institutes under China aerospace science and technology group co., LTD., and commercialized by China four dimensional surveying and mapping technology co., LTD., a professional company under China aerospace science and technology group co., LTD. The successful operation of gaojing I 03 and 04 star marks the completion of China's first 0.5 meter high resolution commercial remote sensing satellite constellation four-star network.
Gaojing 1 is mainly used for commercial purposes. It will provide global users with all-weather remote sensing data service and application system solutions, serving a wide range of traditional and emerging industries such as government management, agriculture, forestry, water conservancy, resources and environment, emergency disaster reduction, Internet and financial insurance.
In fact, it's not just Taiwan. China's satellites have already been able to "see" the world.
Last year on May 19, long optical satellite technology co., LTD., the officer of micro @ long optical satellite released a set of satellite image, jilin, China's most advanced remote sensing satellite, a number of satellites in high definition captured, located in the United States air force base in Nevada in the United States air force combat command and the United States, people's first glimpse of America's most top air force base.
Changguang satellite technology co., ltd. was established on December 1, 2014 and is the first commercial remote sensing satellite company in China. The company independently developed the "jilin no. 1" satellite that captured these exciting images in 2015.
According to the official website of changguang satellite company, on October 7, 2015, the "jilin no. 1" group star independently developed by the company was successfully launched, which set a precedent for the application of China's commercial satellite.
Jilin no. 1, mainly for civilian use, is a ground-to-ground observation satellite, which can provide more accurate geographical information for people, and also realize disaster investigation, food production evaluation, communications and other tasks.
Last year, they also posted clear images of U.S. military shipyards, including U.S. aircraft carriers and destroyers, captured by commercial ground-to-ground observation satellites, according to the observer network.
This time, satellite images were posted at Nellis AFB air force base in Nevada, 13 kilometers northeast of the famous Las Vegas CBD area
4600 hectares.
As an air operations command facility, nellis air force base is home to the U.S. air force's air operations center and is a major training ground for U.S. and foreign military aircraft crews.
The f-15s, f-16s and a-10s, as well as command posts, training centers, hangars and all runways, are clearly visible in the photos. In addition to being invisible from the hangar, you can see about dozens of different types of aircraft.

Sources say the United States is developing a 2.5-meter geosynchronous orbit optical reconnaissance satellite using optical thin film imaging. Similarly, China has developed a single silicon carbide reflector with a diameter of 4.03 meters and a resolution of 2.5 meters for geostationary satellites, and is developing a film mirror with a diameter of 20 meters, a length of 100 meters and a resolution of 1 meter.
Therefore, in this field, China will not only successfully catch up with developed countries, but also enter the leading level, and then it will really be "everything under control".
现如今，卫星导航已经深入到我们日常生活的方方面面，许多人出门几公里离开导航就会迷路，不少国人更是言必称GPS，习惯性的将“导航定位”等同于美国造的GPS。但你不知道的是，智能手机和导航仪的信号来源很可能在几年之间已经“易主”——“中国造”的北斗系统，正在强势进入卫星导航产业。这不，美国GPS刚刚与北斗签署兼容与互操作协议，也算打压不成终于服软了，但这次的合作会影响我军信息安全么？
Beidou and GPS realize compatible navigation and positioning accuracy more reliable
On November 29th, committee wang li, chairman of the satellite navigation system in China and the United States, Jonathan margolis assistant deputy secretary of state under the witness of China's satellite navigation system RanCheng its director of office of management and the state department's office of space and advanced technology David Turner, deputy director of the signed "beidou compatible with GPS signals and the interoperability joint statement.
According to the statement, the two satellite navigation systems have achieved radiofrequency compatibility under the framework of the itu, achieving interoperability of civilian signals, and will continue to conduct compatibility and interoperability cooperation. The beidou satellite navigation system and the GPS global satellite navigation system are radiofrequency compatible under the framework of the itu, and the two systems' civilian signals B1C and L1C are interoperable, the statement said. Users using both beidou and GPS civilian signals can enjoy better services without significantly increasing costs. The signing of this statement indicates that beidou and GPS can achieve signal compatibility in the design and construction of satellite navigation system, further improve navigation and positioning accuracy, and better serve users all over the world.
According to the introduction, the compatibility and interoperability between the two satellite navigation systems is very important. In short, compatibility and operation means sharing together, so that the public can enjoy better services. The realization of compatibility and interoperability between China beidou and the us GPS system will further promote cooperation among members of the world satellite navigation family. China and Russia have already signed an agreement on compatibility and interoperability between the beidou satellite navigation system and the glonass satellite navigation system.
The construction of the beidou 3 global network began on November 5 when two beidou 3 satellites were launched. There is also a planned beidou 3 launch this year.
Beidou's performance is so advanced that, in theory, only three satellites are needed to locate anywhere in the world, and if there are four satellites, enough accuracy can be ensured.
In most cases, the beidou and GLONASS systems are flat, and in some cases the beidou system is superior to GPS and GLONASS systems. Technically, beidou 3 will have 35 satellites in orbit, while GPS and glonass will each have 24. The constellation configuration of the beidou system is also superior to that of GPS and glonas. The beidou system has a high orbit satellite, which is less shielded during our positioning. Because the earth is spherical, if the satellite's orbit is low, the electromagnetic wave propagating in a straight line will be easily blocked when it comes to high buildings. So beidou's high-orbit satellites are much better than GPS and glonass. China has conducted experiments in southeast Asia to prove that the beidou system is better than GPS. The beidou system developed relatively late, but it has learned a lot from the experience of GPS and glonass, so as to realize the backward position.
The launch of beidou 3 will enable a global network, the equivalent of the current GPS, to be used anywhere in the world. The former beidou ii only covers the asia-pacific region in a regional way, and the global network of beidou iii will fit well with the "going global" strategy of One Belt And One Road. Beidou 3 is expected to cover countries along the One Belt And One Road line by 2018, which will have an impact on many of the strategies our country advocates. It's like sharing bikes, they're all being deployed overseas, and if our beidou navigation system hasn't been up to date, these bikes can only use GPS navigation systems overseas.
In the past five years, beidou technology has been continuously integrated with new technologies and economies such as Internet + and big data. This gives the beidou system the opportunity to overtake other navigation systems in the world, such as GPS, and the beidou technology integration new economy will continue to bring better service to users around the world.
Whether military or civilian, the beidou is of great importance to our country, and it is not an exaggeration to call it "a national weapon of great importance". The signing of the compatibility and interoperability agreement with GPS marks a historic step in the development of beidou, which not only reflects the strength and status of beidou, but also shows the strong confidence of China's military industry.
On October 12, 2017, amazon held a new Kindle launch event in Beijing. The release of new Kindle Oasis adopted new 7 "super clear e-ink screens, upgrade intelligent reading lamp, let you enjoy reading brings joy, light metal fuselage design is convenient to carry, the highlight of this design is IPX8 waterproof design, brought disruptive change for reading experience, broaden the reading environment, highlights the theme of the conference--“There is no limit to what you can read”。
Since the birth of nuclear weapons, it has been regarded as a doomsday weapon capable of destroying the world and feared by all countries. In addition to the destruction of heaven and earth by force, the subsequent secondary damage is also inestimable, and the destruction of the ecological environment cannot be repaired for a long time. However, under the pressure of the current international anti-nuclear wave, it has gradually become a decoration for powerful countries to decorate their own national strength. New weapons, such as laser lasers, electromagnetic railguns and other high-energy weapons, were born in their place, as well as science fiction weapons such as the rod of god.
The rod of god, also known as the pestle of god, is a ground-based kinetic energy weapon system that was first conceived in the U.S. military's Star Wars program in the 1980s. This new space-based weapon is fast in reaction and accurate in hit, making it impossible for the enemy to defend. The ability to easily destroy large buildings and underground bunkers hundreds of metres deep after a space launch is a "killer" against strategic targets and does not produce radiation.
Light to hear name must be a great advantage of high-tech weapons, actually otherwise, the principle is very simple, adopt the method of vertical attack, like a meteorite hit the earth, so it is the kinetic energy of the huge, with 11 km/SEC is about 4000 hit the ground at a speed of Mach resulting damage is quite large, its power is equivalent to a small nuclear weapon. It takes only 11 minutes to get out of orbit and hit the ground, less than a third of the time for an intercontinental ballistic missile.
Since the development of the rod of god, some problems may have been solved to a certain extent, but there are still many bottleneck problems that cannot make breakthrough. One is how to launch into position, two is high temperature loss, three is precision guidance. In addition, the effect is unknown, since there has never been a simulation experiment, the attack effect is only a theoretical assumption. And the us military plans to complete the deployment of the staff of god by 2025.
Not only that, China is developing a new strategic deterrent weapon called the rod of god to counter the us anti-missile system, according to Hong Kong's Ming pao newspaper. If the research and development is successful, it will undoubtedly be another sharp edge for China.
A cutting-edge technology has made China less afraid of nuclear bombs: Russia cannot build them
How complex is the technology to spot a newly launched intercontinental missile in space? Previously, only the United States and the former Soviet union had this top technology. Since the Soviet union, Russia has been unable to develop and maintain the world's top technology.
The core component of this technology is the infrared space-based early warning satellite. Now, in addition to the United States, there is another country in the world that can build and launch such a satellite.
In march, the China science and technology daily reported that China now has "vanguard" reconnaissance satellites and "outpost" infrared warning satellites, two types of military remote sensing satellites. It is the first time China has confirmed that it has begun building a global early-warning satellite network that would provide China with an invisible nuclear missile shield.
Currently, only China and the United States have space-based infrared early-warning satellites in orbit around the world. The Soviet union used to have them, but since the Russian era, Russia has been unable to maintain and develop new satellites, so Russia's actual space-based infrared early-warning capability is missing. Although Russia knows the design of the principle, it cannot make it.
What's amazing about the infrared space-based early warning satellite is that it can detect and track intercontinental missiles within seconds of their launch. When a large ballistic missile is launched, it will produce a thousandth degree of tail flame in the rear, which will form a very obvious thermal channel from the ground to the air. The sky - based infrared satellite looks like a shining line.
Space-based infrared early warning satellite using high-speed scanning infrared detector and dual sensor model and narrow field of gaze tracking detector, can to 24-hour tracking of fixed area, the area scanned for generalization of 5-6 times/min, found the goal the first time to switch to the narrow field of gaze tracking detector, 10 seconds will be able to confirm whether a ballistic missile, related parameters for 90 seconds back to the ground, launched by the ground to confirm whether the global warning.
This will give people at least 10 minutes to counter their ballistic missiles. It will be left to the final decision whether to use the interceptor system for multi-layered interceptions, or to launch their own intercontinental missiles to fight back.
Such powerful high-tech equipment is bound to be expensive. Because most infrared early warning satellites in geosynchronous orbit or the far orbit around for a long time running, the required satellite platform is a kind of high load for a long time use to bear a very large platform, and to carry large amounts of star high sensitivity infrared sensor and high-performance on-board processing chip, the equipment cost is expensive.
The average cost of developing a space-based infrared early-warning satellite, measured by America's early-warning satellites, is about 20 billion yuan, or about 28 billion yuan, including the cost of a launch. It would take about 2 billion yuan to launch a civilian satellite that would also be used for broadcasting from space. The big difference is not hard to see how rare the equipment is.
Although China's satellite launch costs are generally lower than those of other countries, China's space industry has historically been able to charge up to 30% less than those of the United States, according to international quotations. In this way, about 20 billion yuan will be needed to launch one, and at least three long-term satellites will be in orbit around the world. Therefore, the system, including the ground supporting construction and the replenishment of the network star, will almost stop at 100 billion yuan. This is by far the most expensive piece of equipment currently in use in China, and even if you look back at China's "two bombs and one star" project, a single atomic bomb or hydrogen bomb would not be so expensive.
But it's also worth it. Without such a global warning system, americans would never have recognized your anti-missile capabilities. Recently, foreign media have announced the successful intercept of China's "hongq-19" anti-missile intercepting test "4-f4", which is the best demonstration of the effectiveness of China's space-based infrared system.
Therefore, it is quite necessary to establish a space-based global icbm early-warning system in order to prevent the situation of launching icbm directly against other countries. That's what China, the most expensive satellite in history, is all about, being able to hold a nuclear umbrella over your head, a spear and a shield so that you don't have to worry about people Shouting about a nuclear strike.
According to a report in the December 2017 issue of the Canadian han and defense review, the Chinese h-20 strategic bomber is still in the final design stage and has not yet produced a prototype. Due to confidentiality and other reasons, any so-called model and pictures of h-20 on the Internet are not true.

Hanhe said the magazine had exclusively reported on China's launch of a new strategic bomber five years ago, after the Chinese air force set out plans to develop the new strategic bomber at a previous air force equipment conference.
Hanghe said its sources said the meeting first established the military strategy of the Chinese air force: the air force is a strategic service, and it should be able to independently complete a series of strategic strike missions planned by the central military commission, including nuclear strategic missions, as well as carry out strategic strike missions jointly with other strategic services. Therefore, the strategic equipment of the Chinese air force must meet the requirements of the air force strategy.
The PLA air force has set up a total of six strategic equipment development goals, including strategic bombers, strategic early-warning aircraft and strategic anti-missile missions, hanhe said, adding that the development of strategic bombers is an important part of the development of strategic equipment. Han said China's h-20 strategic bombers, infrared warning satellites and a new generation of strategic anti-missile systems could soon be seen.

According to the report, the establishment of the air force strategy has made the United States the primary target of strategic weapons of the Chinese air force. The so-called "strategic weapon" refers to a weapon that has the ability to attack strategic targets with both long-range and nuclear capabilities. H&h stressed that the h-20 strategic bomber was identified as a strategic aircraft capable of both nuclear and standby strikes against the United States at the outset of the program.
The approval five years ago led the Chinese air force to set the basic goal of developing a new generation of strategic bombers within 15 years. According to hanhe, the development of the type 055 missile destroyer and the j-20 fighter jet shows that the development speed of the h-20 may be faster than expected due to the sufficient funds of the Chinese military and the development experience of the y-20 large transport plane.

Han said that while the h-20 will not adopt the design concept of tu-160, China may still study the aerodynamic shape of the u-160 and the idea of weapon strike in order to better design the h-20. The emergence of the h-20 means that China's strategic air force will soon have the capability to strike the United States from the air with both its nuclear capability and its nuclear capability. It will be able to form a real triad nuclear strike capability against the United States.
Although China will certainly not fully copy the b-2 stealth bomber, it is undoubtedly an important reference model in China's development of strategic bombers
Han he believes that the mission planning of the Chinese air force determines that the h-20, which has been basically designed, must have the following tactical characteristics and requirements:
1. With the capability to carry six kd-20 cruise missiles, the range is over 5,000 km, and the range is over 10,000 km after refueling in the air
2. Equipped with two stealthy bomb pods, capable of accommodating at least 6 kd-20 cruise missiles with a range of close to 2000 km, with a payload of not less than 25~30 tons
3. With supersonic capability and stealth capability, but due to the gap in material technology, it may not resemble American b-2 stealth bombers
4. During the test flight, the h-20 is likely to be Russian d-30-kp2 engine, while the mass-produced h-20 is likely to be made in China
5. The h-20 will be more confidential than the j-20. Even the production prototype will only be parked in the factory as the b-2 did in the previous year. Currently, the various h-20 models and satellite images exposed are not real
H&h also said the h-20 bombers would be difficult to design if they were to have the capability to strike the U.S. mainland.
