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.

What kind of microelectronics?
 
You guys want to discuss without figures, or sources. I want to add some of those to the discussion
thanks. I think we all know that: resolution about 50m, working at geostationary orbit.
 
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.


I don't think there is a 50% detect on carrier. You either detect a carrier or don't.

thanks. I think we all know that: resolution about 50m, working at geostationary orbit.


I think, GF 4 will perhaps be an experimental satellite of sorts, because I seriously doubt it can detect a aircraft carrier which will be 6 pixels long. Perhaps down the road we will have a geostationery satellite with a 5m resolution, which will seriously make a difference.
 
Gaofen-1 is better in resolution, I think GF-1 could take some picture of aircraft carrier with resolution 2m pan
Google satellites have even better resolution with 0.25m

Vietnam has VnRedsat-1 with resolution 2.5m

One would expect this kind,

Radiation hardening - Wikipedia, the free encyclopedia

Radiation hardening is the act of making electronic components and systems resistant to damage or malfunctions caused by ionizing radiation (particle radiation and high-energy electromagnetic radiation),[1] such as those encountered in outer space and high-altitude flight, around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare.​

You are mistaking satellites here. Gaofen 2, as far as I remember, can take a 0.8 m picture, while Jilin 1 can take a 0.72 m picture. But they are all SSO satellites. Not in geostationery orbits.

And it matters, because SSO orbits are usually around 500 to 800 km in height, while Geostationery is at 36000 km. That is quite a huge difference.

the lower-orbit satellite has much better resolution. But given its orbit height, it could only take picture of a very small area. In addition to that, it is a "moving" satellite, i.e. it could stay above of a specified area for very short time.

So you could either:
Option 1: launch lots of lower orbit satellites to make sure a 100%/24hour coverage! But it is an expensive way!

Option 2: launch a geostationary orbit satellite. Given its height (36000km), it could monitor a very large area, but with much lower resolution. However, its key task is not to assure a 100% accuracy, but to specify areas that "suspicious". After the suspicious areas specified, it is other low-orbit satellite's job to identify if there is really carrier there! Once other measurements matured, e.g. WU14 (Hypersonic Glide vehicle), they could also join the 2nd round, or even 3rd round search.

Yes GF-2 better than GF-1.
I must name some of them as "able to detect an aircraft carrier" , GF-4 can't

Can you point out anything from this?

But I have recently heard multiple reports of many Chinese convicted in US for trying to export radiation hardened chips to China. Why would China need to import them, if it makes them?

who is china? from what i've read those people just wanted to create new startup in china and make quick money. it's more to do with personal greed... those stuff might be useful for military or might not. they have no connection with chinese gov whatsoever. lol. why everything is china china china china...china ?:rolleyes: :lol:

It would have been understandable if there was only one case, but I read about at least 4 distinct cases.
