China's Space Program Thread II

[by78]

LandSpace gave a presentation at industry event where it gave a first peek at the Zhuque-3 (ZQ-3) reusable rocket. Expendable version has a payload capacity (to LEO?) of ≥20 tons; reusable version has a payload capacity of ≥16.5 tons (when landing at pre-designated landing zones/on recovery ship) or ≥11 tons (when landing back at launch site).

A peek at LandSpace facility being built at Jiuquan launch center:

According to LandSpace, in the next five years launch capacity by private Chinese launch providers will reach 100 launches per year (1000 tons per year), with average launch price of 20,000 RMB per kilogram.

BIG NEWS: Huawei has already tested its prototype constellation LEO satellite. Indicating the company will step into the constellation business. Very good, I don't think a SOE like Satnet/Guowang can compete with Spacex/Starlink. Need to be a private company like HW.

You are like saying "Verizon can not compete with Nokia". Satnet and Guowang are operators like Verizon and ATT, they are not equipment providers like Huawei and Nokia. You are comparing orange and water.

SpaceX/Starlink is both equipment provider and operator, it is an unique case in the whole world including USA. It is equivlant to Huawei, China Mobile and CASC combined. Comparing SpaceX/Starlink with ANY other companies in telecom is absurd, not only with Satnet/Guowang, but also Verizon, ATT or Ericsson, Nokia.

Just so you know, as long as the current regulation of PRC goes, private entities including Huawei will never be in the telecom business as Satnet and Guawang, just like it is not competing with China Mobile or China Telecom. No matter how much you want, telecom as a stratigic domain like energy/power grid etc. is not something that private capital is allowed to touch, unless you get rid of CCP.

Please drop your holy bible of private company is better than SOE. The world largest mobile operator is China Mobile, the larget commercial bank is ICBC, the larget HSR producer is CRRC, all SOEs. They are capable of beating every private companies if EU and US drop their tariff or regulatary obstacles. Also you need to stop the riligious like chantting of SpaceX and Huawei are god like almighty genius. I repect them a lot for their achievement, but you are like having a fetish on them. In case of Huawei, it makes the receiver/switch/transponder as the payload on a sattelite platform. Did Huawei design and make the sattelite? If we take the whole sattelite as a product like iPhone, what Huawei presented is the like the modem or CPU, not the whole phone.

It is a bit strange for LandSpace to present such figure as lauch cost, they certainly have a target of their own, but how could they get a figure on behalf of all potential Chinese launchers.

Assuming this is their own intended price offer to customer, does anyone have a figure of falcon 9? I remember SpaceX charge on payload mass regardless new rocket or reused, so we should be able to have a figure per kilogram.

Possible Fractional Orbital Bombardment (FOB) test. Let's see if it hit its target this time.

There is no need to embed the entire Twitter thread. It's messy looking and clogs up precious screen real estate. Please summarize the information briefly and then provide one link, which is more than sufficient. Thank you.

Huawei indeed shows off the results of its LEO satellite testing project with Harbin Institute of Technology (HIT)..

so what is this presentation for ? it means something happening

agreed with your here. but anything is possible. don't be surprised if Huawei get special permission considering China is in Tech Race with USA especially in 4th industrial revolution. so assistance from private tech giants is necessary. China's 70 percent technological innovations/Patents comes from private sector.

Some images of YF-100 engine tests. The 6th Academy of CASIC has further optimized its test procedures and as a result, it has shortened the acceptance test time for YF-100 engines, which now takes only two days per engine.

Thanks for that information. I have also heard that the sattelite is made by HIT and launched in June 2023 as 龙江三号试验卫星 (LJ-3), by a KZ-1A.

The attached image is broken. Can you repost it?

The presentation is the result of Huawei's payload, it works as expected. Don't know if that is your question.

PRC giving up control of strategic sectors to private company is not much different from CPC giving up its rule. So although from a pure debating point there is a possibility, but I will just leave it like that.

Using Ka band, achieved max 660/135Mbps down/uplink speed!

Covers both VSAT & phased array users Uses experimental Longjiang-3 (龙江三号) flat-type LEO broadband comsat

what does all development mean ? it means something happening. HW is testing satellite based internet

under the supervision of Party's committee. i don't see anything wrong in this. HW only brings tech and expertise.

thanks. Unfortunately it doesn't say much than what I already know.

Here is a Huawei paper on their 6G VLEO satelite design, which is impelementation proposal to 3GPP.

The satelite UE (user equipment) is to use the same air interface as a land based mobile phone except the frequency band is Ka. The UE antena is around 0.5 meter which is apparently not for hand held mobile phone. I am interested in knowing the size of the SAR UE in the slide (the one on the right to VSAT UE).
