You are an idiot, and perhaps weren't able to understand what I said in first go.

For an idiot like you, I will try it once again.

GF 4 is a geo stationery satellite. All the rest, GF 8 and 9 are in SSO orbits, which is usually between 400- 1000km. While Geostationery is 36000 km.

The advantage with Geostationery is that it is fixed in space relative to surface of Earth, and hence can be used for non stop coverage of a particular area.

My point is not for you a typical idiotic indian troll to understand that we have deployed a lot of Gaofen satellites in the 2 years alone that have good enough resolutions to ID hostile subjects as we wish let alone gaofen 4

And my point was still not received by you idiot, that no matter how many satellites you place, a geo stationery satellite has its significant advantages. Any satellite in SSO, will pass over a point, (if it is in the orbit), 12-14 times a day.

We heard many marketing about China ability in those.
Like, China tracked US F-22/B-52, China helped to find MH-370, China control the Senkaku airspace, China found American submarines, China tracked America aircraft carrier, China intercepted ICBM, China tracks Vietnam military movements ...

Now it's time for discussing about them on:

- Proven performance of those.
- Relevant cases.

According to a Nov. 10 China-based article in the Global Times, a Shandong Province-based JY-26 recently monitored an F-22 flying to South Korea. Separated by the Yellow Sea, Shandong’s coastline is 400 kilometers from Kunsan Air Base and Osan Air Base, South Korea.

Netizens Unhappy Over China's Muted Response To US B-52 Air Defense Zone (ADIZ) Flyover In Disputed Islands

China’s muted response brought criticism from some sections of the State media. On Thursday, officials in Tokyo said Japanese Self-Defence Forces had also flown through the zone – parts of which overlap with Japan’s ADIZ – without notifying Beijing, and “no response was detected.” The ADIZ includes the disputed Diaoyu or Senkaku islands in the East China Sea, over which both countries have competing claims. In recent months, naval vessels from China and Japan have had run-ins in the waters off the islands, while Japan recently threatened to shoot down Chinese drones over the area.

South Korea’s military said it conducted a surveillance flight through the zone “without informing the Chinese authorities,” the Seoul-based Yonhap news agency reported, adding that the flight was “a clear sign” that the government would not follow China’s regulations.
After Saturday’s surprise announcement brought concerned responses from the U.S., Japan and South Korea, China on Thursday issued a muted reaction to the South Korean flight.

A Chinese netizen posted this in the incident Myanmar bomber invaded and drop bomb to China civilians.

Some Chinese generals are going to be demoted or charged over this.
The Myanmarese have accidently exposed serious Chinese vulnerabilities in their air defence.
Maybe it is possible that MH370 flew into China undetected after all.

That's just one way statement, we could discuss to know more on this, make clear the situation and find out the true performance of Great China equipments.

Google's Satellites Could Soon See Your Face from Space

Written by
Elyse Wanshel
August 11, 2014 // 02:03 PM EST

Google will soon have an unprecedented ability to spy on you from space. Theoretically, at least. How?

Two months ago, after much lobbying by the biggest satellite company in North America, DigitalGlobe, the US government relaxed restrictions to allow for commercially available satellite imagery up to 25 cm resolution—twice as detailed as the previous limit of 50 cm.

Now, the first commercial satellite set to capture these high-res images, DigitalGlobe's Worldview-3, will launch this Wednesday. Six months after that, private businesses willing to fork over the money will be able to get their hands on hyper-detailed photos and videos of the globe.

That, of course, includes Google.

Google—along with Microsoft, NASA, and numerous US federal agencies such as National Geospatial-Intelligence Agency, which played a pivotal role in the seizure of Osama Bin Laden—is a regular DigitalGlobe customer. It signed a multiyear imagery contract with the colossus satellite company in February to use satellite imagery for apps like Google Earth, Maps, and Street View.

The extra sharp images from Worldview-3 will greatly increase the maps' level of detail to the point where it can make out 10-inch objects, which means Google will soon be able to see “manholes and mailboxes” from its hired eyes in the sky.

So, when you get that panicked feeling mid-flight that you forgot to turn off your coffee maker before leaving on vacation, Google will have resolution adequate enough for you to see a recent image of your slowly singeing house. You could also hypothetically pull up Google Maps and see a real-time image of your actual plane, rather than a blue dot, soar further and further away from your fiery abode.

The satellite behemoth is now making a push to relax the rules even further, down to 10 cm resolution, about the height of an iPhone 4.

DigitalGlobe currently has five birds in the sky, and one, GeoEye-1, has the ability to capture images at 41 centimeters. The company lobbied hard to loosen restrictions to 25 centimeters so that it could compete with foreign firms that will be blasting their own satellites into orbit soon. According to Reuters, the ability to commercially sell hi-res images this small, it can possibly increase the DigitalGlobe’s revenue by $400 million.

Meanwhile, coincidentally or not, Google acquired its own private satellite company, Skybox Imaging, shortly after the US government relaxed its satellite imagery restrictions in June.

Google’s Skybox intends to launch a constellation of 24 satellites by 2018, which will survey the globe by taking pictures of its entirety three times a day. This too will eventually, undoubtedly, upgrade the picture quality on its map applications. Google’s own birds can capture 90-second video clips and imagery at 30 frames per second. But how much can they actually see?

At this point, considerably less than the shots the Worldview-3 will be snapping. Skybox’s satellites deliver high-res imagery "better than 1-meter resolution,” said Sara Blask, a company spokesperson. “Which means you can clearly discern features such as the size of car windshields, road markings and car colors.”

Skybox founder Dan Berkenstock echoed this claim in a TED Talk he gave right before the launch of SkySat1: “From our own computer simulations we quickly found that one-meter really was the minimum viable product to be able to see the drivers of our global economy,” he said. “For the first time being able to count the ships and cars and shipping containers and trucks that move around our world on a daily basis while conveniently still not being able to see individuals.”

That last bit is the salient point: Skybox’s satellites cannot capture details as small as license plate numbers or someone’s face—yet. But DigitalGlobe’s might. At 25 centimeters, the images will be detailed enough to classify the make of a car. If the restrictions relax further, the plate number or owner's face could come into clear view.

Naturally, the mere speculation of how this new powerful view will impact privacy is already raising concern. But how the Silicon Valley company actually intends to use its new detailed view of Mother Earth is still a looming question.

Google, for its part, claims it will use satellite image and video capabilities for the greater good. The technology can be extremely helpful in regards to natural disaster relief and it could provide internet access to places where it was previously unavailable.

In all likelihood, Google acquired Skybox not to spy on your mailbox number but to help it achieve something it has not yet been able to do: create a competitive cloud service. Skybox plans to combine its snap-happy satellites’ images with a collection of public data it has already gathered, like historical weather reports and satellite imagery, and create a vast archive, or a “cloud for the Earth” for other companies to run their own software and algorithms on.

But that raises another question: What kind of companies will utilize this “cloud for the Earth?” What could they potentially create with this vast amount of knowledge that, until now, seemed only obtainable and appropriate for super powers or leather-clad spies in action movies? If Google can make out your face from space, will it? And how might it capitalize on that ability?

Despite much of society’s indifference about sharing personal data—proven through social media’s mass archive of photos and information—perhaps it’s time we begin to have an open conversation, on an international level, about these new technological developments that can impact the world and public’s privacy. The sky is no longer the limit.

The advantage with Geostationery is that it is fixed in space relative to surface of Earth, and hence can be used for non stop coverage of a particular area.

GF-4 has the resolution 50 meters, that means very low resolution, because in the imaging device on it, 1 pixel = 50 meters in real. So 300m = 6 pixels, estimated it's equal the dot in "i" .
It could be mixed with photo noises which self-generated with distance, light condition, ...

Recommend that you use cloth to wipe your screen to able to realize something in the high noisy photo.

 

[Brainsucker]

To be honest, what is you real intention to come here in the China Defense Forum Section? Because it seems that you don't have any sincere motive to discuss this matter with other Chinese military fans here. Do you really love Chinese military hardware? Nope. You just want to mock the community. and create a thread to fight the community. So basically, you are a Troll. Someone who come to disturb the community with bad intention.

Remember this is Chinese Defense forum section. It is the place where the people who like Chinese military hardware. Not someone who mock them.

So l will call the mods and let them decide if you're a troll or a Chinese military fan.

YJ-26 claimed to be able to monitor stealth F-22 400 km away

Operating in the long wave band – VHF/UHF enables the JY-26 to detect targets presenting low radar cross section (stealth aircraft) at the decimetric, centimetre and millimetre wave bands. The use of phased array technology also provides users the ability to increase the power transmitted at a certain location where a target presence is suspected, thus increasing the probability of detection of low-RCS targets.

The manufacturer also claims the radar is designed with robust anti-jam and electronic counter-countermeasures, enabling it to face strike forces conducting advanced anti-access/area denial (a2/ad).
It is using advanced, two dimensional digital, active phased array system, enabling high accuracy, target tracking and separation as well as operation at long ranges of up to 500 km.

The US is currently deploying advanced stealth aircraft in the Pacific, including B-2 bombers and F-22 Raptor stealth fighters. Both have also deployed on missions near China, providing the Chinese the opportunities to test their new radars against those planes.

Chinese designers at the Airshow China claim the JY-26 radar has already spotted the US Air Force most advanced stealth fighter – the F-22 Raptor stealth fighter, as it flew in South Korea on recent exercises. The radar is being developed at Shandong, located just across the Yellow Sea, separating the Korean peninsula from mainland China.

it can't

Some times I just could not understand why you want to engage in a discussion that you almost know nothing about!

GF4 is a geostationary satellite. It stays on an orbit of 36000km, higher enough for it to cover a very wide area, e.g. the entire Pacific Ocean.

50m resolution seems to be low, that is true. But it is already sufficient enough if China just needs to know if a particular area has some possibility with the aircraft carriers inside it. Once GF4 tells China that a large-sized vessel is moving at a specified area (it may be aircraft carrier, it may be not), China will send lower orbit satellites to that area to do a further search. Moving forward, even hypersonic vehicle, like WU14, could join this effort! This is the power of system! Not as simple as one single satellite vs. the entire navy fleet!

Just imagine, a camera with 50m resolution at a 36000km orbit, if we put this camera at a 300km orbit satellite, what the resolution could be??

China’s Space Station Planners Put out Welcome Mat
by Peter B. de Selding — October 13, 2015

JERUSALEM — China is soliciting international participation in its future manned space station in the form of foreign modules that would attach to the three-module core system, visits by foreign crew-transport vehicles for short stays and the involvement of non-Chinese researchers in placing experiments on the complex, the chief designer of China’s manned space program said Oct. 12.

But he declined to commit to an international orbital docking technology that would facilitate international participation in the Chinese facility.

The Chinese orbital station, consisting of a core module and two experiment-carrying modules, can be expanded to a total of six modules if international partners want to invest in their own components, said Zhou Jianping, chief designer of the China Manned Space Program at the China Manned Space Agency.

Artist’s concept of Chinese space station.​

Addressing the 66th International Astronautical Congress (IAC) here, Zhou said the station will have a nominal crew of three, with a maximum capacity of six, with three-member crews being launched aboard Chinese Long March 2F rockets from the Jiuquan spaceport for missions of up to six months.

China has signed initial space station cooperation agreements with the Russian and European space agencies, and while the European Space Agency has begun training astronauts in Chinese, there is no specific plan yet to send astronauts to the Chinese facility.

The core module of the Chinese station is scheduled for launch in 2018, Zhou said. Crew-carrying Chinese capsules will visit the module before the two experiment modules are added to complete the initial station design.

“Work is well under way,” said Zhou, whose education includes time at the University of Southern California. “All the modules and associated vehicles are under development.”

If the current schedule holds – he gave no indication of any financing or technical roadblocks – the station would be ready for full operations “around 2022,” he said.

One of the interesting features of the Chinese space station is that it will be served from two of China’s four spaceports.

The cargo modules will be launched aboard Chinese 5B rockets from the Hainan spaceport in southern China, at 19 degrees north latitude. Pressurized and unpressurized cargo will be launched aboard Long March 7 rockets, also from Hainan.

But China’s Shenzhou crew-transport vehicle is launched from the Jiuquan launch facility at 41 degrees north latitude, in the Gobi Desert of Inner Mongolia.

The station will operate for 10 years or more, at an altitude of 340-450 kilometers with an orbital inclination of 42-43 degrees relative to the equator.

The international space station managed by the United States, Russia, Europe, Japan and Canada, operates in low Earth orbit of around 400 kilometers in altitude, with an orbital inclination of 51.6 degrees, an accommodation to Russia, whose Baikonur spaceport in Kazakhstan is at 46 degrees north latitude.

Zhou said China plans to launch an astronomy telescope into an orbit near enough to the space station to dock to it for upgrades and servicing. He declined to specify the telescope’s size.

Zhou also declined to say whether China’s station would use a technical standard being developed in Europe and the United States that would facilitate future interoperability of orbital stations through common docking technologies.

The annual IAC conferences are routinely filled with commitments to international collaboration from national space agencies. A common docking standard is one of the few concrete examples of progress in this respect. A Chinese refusal to adopt it – Zhen said his office would need to assure its quality – would send a signal about China’s intentions with international partners.

So to you, the answer is "It can't"
By the way, what you mean with "send lower orbit sat to that area" ?

In a recent issue of the Chinese-language state-run China Youth Daily newspaper, a report claims that the Gaofen-4 geostationary earth observation satellite will be launched by the end of this year with the express purpose of hunting US aircraft carriers. The satellite is equipped with a visible light imager at 50 meters and infrared staring optical imager at 400 meters.

 

[GS Zhou]

So to you, the answer is "It can't"
By the way, what you mean with "send lower orbit sat to that area" ?

The task for Gaofeng 4 is not to do a 100% clear detect on the carrier. It is only a small part of a huge system that aiming at destroying the air craft carrier. Therefore the question itself is not solid.

The responsibility for Gaofeng 4 is to remind China where are the areas with possibility to see the carrier. Once some potential areas identified by it, China will make other lower orbit observation satellites moving to the areas to do the next step search. Just like the MH370 case we just discussed.

Russia Says Preparing Rocket Engine Deal With China
By Matthew Bodner Oct. 12 2015 17:09 Last edited 17:09

Russia is preparing a deal to sell its highly capable rocket engines to Beijing in return for access to Chinese electronic components used in spacecraft construction, Russian Deputy Prime Minister Dmitry Rogozin said on Monday, the TASS news agency reported.

Discussing prospective Russian-Chinese economic projects at an expo in the Chinese city of Harbin, Rogozin said the two sides were pursuing cooperation in the field of spaceflight — a sector that both countries are keen to develop.

“We are talking about an agreement to supply Russian rocket engines [to China], and the reciprocal delivery of Chinese micro-electronics that we need for things like the construction of spacecraft,” Rogozin was quoted as saying.

The deal would be a big win for Russia's ailing space sector. Although the industry produces rocket engines that are regarded as some of the best in the world, the only foreign customer is the United States, which uses them for both military and civilian satellite launches.

This connection between the U.S. and Russian space industries became a source of tension during the Ukraine crisis last year, after Rogozin threatened to end sales of the engines in response to Western sanctions against Moscow.

The rhetoric faded over the course of 2014, as both sides realized the existing arrangements were mutually beneficial, and Russia had no other customers lining up to buy rocket engines en masse.

But a supply deal with China could give Russia additional leverage over the U.S. space industry.

Rogozin on Monday said the two countries were working on an agreement to be signed during Prime Minister Dmitry Medvedev's visit to China in December.

He also announced that the two sides planned to launch a joint venture specializing in the production of microchips and receivers for the Russia's Glonass satellite navigation system and its Chinese analogue BeiDou. Both are marketed as alternatives to the U.S.-operated Global Positioning System (GPS).

Russian-Chinese bilateral economic and technological ties have grown in the wake of Moscow's falling out with the west over Ukraine, and the two countries have discussed several ambitious long-term space projects that could be pursued together, such as a lunar exploration program, Rogozin said.
