>Long March 3B lofts Gaofen-4 to close out 2015
>The Chinese have closed out the year with the launch of its Long March 3B/G2 rocket. The launch involved the orbiting of a geostationary remote sensing bird, known as Gaofen-4 (GF-4). It was launched from the Xichang Satellite Launch Center at 16:05 UTC.
>Gaofen-4 is China’s first geosynchronous orbit remote sensing satellite featuring a visible light and infra-red staring optical imager with a common optical system.
>The optical resolution is better than 50 meters, while the infrared resolution is better than 400 meters. GF-4 can provide an imaging area of 7,000 km × 7,000 km with individual scene covering an area of 400 km × 400 km, and with capacity for high temporal resolution remote sensing monitor at minute-level. Launch mass is 4,600 kg. Gaofen-4 will be operational for 8 years.
>The satellite combines the capacity of extremely high temporal resolution and high spatial resolution, optimal features that have various applications such as disaster monitoring, meteorological observation, agriculture, national security, etc.
>>28357248
Basically, it will be deployed in geosynchronous orbit, staring 24/7 with a very high resolution camera (compared to other geosynchronous optical satellites, whose resolutions are in the hundreds of meters) at the South China Sea, West Pacific and the first and second island chain for... "disaster monitoring, meteorological observation agriculture, national security"
No satellite passes required, no "down-time", and outside of the range of all Western-deployed ASAT systems.
The ASBM kill-chain has another asset.

America can never reach it.
Every single US warship will leave behind a several km long wake that will be easily picked up by this satellite. Huge carriers will be even easier game.
>>28357267
All naval assets sailing within this radius can become WU-14 food 24/7.
This will provide targeting data for the DF-21D

>>28357341
Yes, this geostationary system pretty much functions as a persistent space-based AWACS staring down on an entire region 24/7, while the lower-orbiting 29 birds of the Yaogan-series NOSS (with a lot higher sub-meter resolution) will pass the region as well and confirm the imaging data of the GF-4.

>CVBGs cannot hide anymore!
Hmmmm....
If only there was a hero among us, a poster that warned us about things like this...
Bah. I'm not butthurt. I just like this picture a lot.
i don't think anyone was under the impression that a cvbg could "hide". df-21d relies on a lot of links in a chain to get a kill, any one of which being disrupted/taken out fucks the entire deal...
>>28357505
not to mention the entire premise of using ballistic missiles against a carrier group is kinda retarded. at that point we're all fucked.
>>28357280
Because it gets fucking stale after the third or fourth time.
It's kinda pathetic, really.
>China is the first ever country to use geosynch spy satellites.
Okay, sure.
Meanwhile in America...
>>28357559
>China is the first ever country to use geosynch spy satellites.
No, the US and most Western countries do so as well - but they use weather satellites that have only a resolution in the magnitude of kilometers.
The GF-4 has 20 times the resolution of GOES or MSG, two western geostationary satellites.
The GF-4 is the first ever "civilian" Earth observation satellite worldwide in geostationary orbit that isn't meteorology specialized and has such resolutions. 50m might not seem like much - but a carrier with its 300m length will still be detected by it - not to mention its several kilometers long wake.
The Chinese have plans to launch more and better Geostationary satellites to orbit in the future, featuring telescopic lenses that gives them sub-meter resolutions.
Please keep your threads to the weekend, fiddy.
Or at the very least get a new format, this is boring.

Search your heart, you know it to be true.
>>28357794
We can't say for sure what the US military uses. They deployed multiple classified payloads with the Space Shuttle, so we don't know what they have.
>CVBG cannot hide anymore
>Geosync satellites providing anything but outdated info on a fast vessel.
Not even Russians brag about that shit. Enjoy hitting water.
Cant wait for it to appear in CMANO
My scenario will stand even more.
With the GF-4 I dont have to wait for an odd Yaogan satellite to make a pass to detect the CVBG anymore...
>>28357839
My personal favorites were the claims about the 'inabilities' of SM missiles.
>>28357853
No, with geostats, the entire point is that the satellite information will not be outdated anymore. It is after all a camera that is staring down 24/7 on a fixed area and can detect every single movement there in real-time.
It does not "pass over" the target area - it stays consistently above the target area for the entirety of its service life.
Chinese commanders in the future could basically play Command and Conquer styled RTS in real battle with only a few of these geostats in orbit, bearing different orpitcal or radar payloads.

Using ballistic missile when you are a nuclear power is retarded. It is just asking for you enemy to immediately escalate to a nuclear response.
isn't the whole point of aegis, anti-ballistic missiles?
>>28358427
Nah, the SM-3 is the primary ABM for the Navy.
If only America built some kind of drone spaceplane years ago capable of attaching a remote-activated demolition charge to the satellite and flying away, leaving it in place for a signal in time of war.
China: the US Navy's greatest weapon in the war against budget cuts.
You know it's true.

>Micro-satellites[edit]
>A Micro-satellite is defined as any object orbiting the earth that has a mass greater than 10 kg and less than 500 kg.[9][full citation needed] This includes man made satellites and natural satellites, like debris. While man made micro-satellites are primarily peaceful, they are easily weaponized. Because of a satellite’s high relative velocity to another satellite, any collision would destroy both satellites, and micro-satellites have the advantage of being cheaper, more maneuverable and harder to track. In 2001, a Chinese newspaper stated that the PRC was testing a parasitic micro-satellite that could latch onto another satellite and destroy it on command.[10] While no evidence has been found to demonstrate the development of such a parasite system, in 2008 the BX-1 micro-satellite released by the PRC passed dangerously close to the International Space Station at a relative speed which would have destroyed both objects had they collided.[11] This close call raised awareness of the PRC's ability to use micro-satellites as a kinetic kill ASAT system.
>>28358838
Yes you did.
>>28359043
>ramming a sat with another sat
In that case, every sat is anti sat. Unless you plan on hitting an active manuvering X-37B, in which case L E L.
>>28359148
Its not realtime, friend, there is a significant delay and thus cannot be used as a targeting guide, just detection.
>>28359200
That's why they developed the LM-6 ORSS rocket which can be readied in short time, launch from a military-grade TEL and release up to 20 micro-satellites per payload, laying an orbital mine-field of maneuverable sensor-guided kinetic kill satellites.

>Debut launch of Long March 6 deploys 20 satellites
>>28359234
You do realize how small a number 20 sats are for something as large as space, even in orbit.
Unless you plan on kesslering LEO, its pointless.
>>28359259
*pointless for the X-37 with its high transit.
For Normal sats its ok.
>>28357852
>In 2011 the agency donated two space telescopes to NASA. Despite being stored unused, the instruments are superior to the Hubble Space Telescope. One journalist observed, "If telescopes of this caliber are languishing on shelves, imagine what they're actually using."
http://www.popsci.com/technology/article/2012-06/nasa-adopts-two-spare-spy-telescopes-each-maybe-more-powerful-hubble
That was in 2011, and the telescopes were made in the 90's.
Whatever the Chinese have in space, the NRO has something way better.
Daily Reminder: the NRO's budget is the largest of all the intelligence agencies. Bigger than the NSA, bigger than the FBI, and bigger than CIA.
>>28359259
These are 20 of mixed sizes. Some of them were larger and some smaller. With an uniform size, the LM-6 and similiar fast response rockets could launch more than 20 per shot.
>>28359299
If you already have sub-meter resolution telescopes, anything better will hardly make a difference. China and US both have spy satellites in the sub-meter category. Anything below that is pretty much of negligible use.
>>28359314
Yes, again, the carrier rocket itself is not going everywhere, its going to one point in space, then releaseing its payload.
Its not like the small sats will have a large amount of manuvering fuel, so they will lay like mines and wait for something to come close.
Its an open secret the NRO has sats specifically to watch other sats, so the 37 could use its very large fuel reserves to simply go somewhere else, or if not, simply go back in atmo.
Now, if you are going to Kessler LEO, different story. But that fucks china as hard as the US and the world.
>>28358702

There is literally nothing for humans to do in geosynchronous orbit.
>>28359479
But it is true.
DARPA has been working on the MOIRE, but it is still way off.
At the moment, military satellites or optical satellites with resolutions below 100m are limited to low earth orbit/sun-synchronous orbit satellites that only pass a certain area once or twice a day.
>>28359515
The fact you claim to have an inkling of the capabilities of NRO sats is fucking hilarious anon.

At the moment, only weather satellites are in this orbit. China's the first.

Also, Geostationary/Synchronous orbits have severe limitations in terms of positioning. You can only achieve the effect of geo-synchronization if you place your satellite directly along the equatorial line. US refrained from doing that, since the USSR is way north of the Equator. So, the Cold War had no geostationary spy sats due to the simple reason that Russia's reach never extended down south.
But for China, the Equator-region is very interesting, because the SCS and much of their sphere of influence can be covered by satellites orbiting the Equator.
>>28359442
I doubt any fucking spaceplane can make it to GTO m8
Unless it has boosters on it, myb
>>28359667
You are talking about the military capabilities of a civilian sat.
When actual military sats exist.
You are posting the semple tank and claming its better than an M1A2 because we dont know the exact armor makeup and RHA thickness on the M1A2, but do on the semple tank.
Also, you can incline geosynchronous orbit all you want, you idiot.
The word you want is geostationary.
>>28359774
Geostationary and Geosynchronous are both names that mean the same, genius.
>Also, you can incline geosynchronous orbit all you want, you idiot.
Not really. Sure, you can incline your satellite, pointing his aperture towards the north or the south, but you cant really incline the orbit.
>>28359813
>Geostationary and Geosynchronous are both names that mean the same, genius.
Why dont you look that up, dumbass.
>A special case of geosynchronous orbit is the geostationary orbit, which is a circular geosynchronous orbit at zero inclination (that is, directly above the equator).

>A geostationary orbit is a particular type of geosynchronous orbit, the distinction being that while an object in geosynchronous orbit returns to the same point in the sky at the same time each day, an object in geostationary orbit never leaves that position.
Back at you.
Both need to be fixed above th equator.
>>28359897
Yes, you correctly identified that they are not the same, you moron.
>>28359688
You can mount it on any stack you want. It's not like that thing launches from a runway. It's launched exactly like any satellite.
Which is the appeal. Nobody can tell it apart from any other polar launch until it starts to maneuver, at which point the damage is done.
>>28357938

Try reading it again.
>>28359915
They are basically the same. You cant do shit about them being fixed to equator-orbit (ie. not passing Russia in a hundred years)
YOu can play around with the inclination of the satellite itself, making it point towards any position while it is fixed above the equator, but you cant just make it fly above the Arctic region to stare at penguins.
