While there are open questions on how China will use its satellite tv for pc megaconstellations, their deployment would require a big improve within the nation’s launch capability, driving the event of latest business rockets, together with reusable boosters, to decrease prices and improve their flight charge.
The Long March 5B rocket, developed by China’s incumbent state-owned launch firm, is just not probably the most cost-effective of those choices. But the Long March 5B has the raise capability to haul extra Guowang satellites to orbit than every other operational Chinese rocket. It’s doubtless future satellites for Chinese megaconstellations will fly on a number of varieties of rockets as extra launchers come on-line.
China has till 2032 to launch half of the Guowang constellation—6,496 satellites—in line with radio spectrum laws promulgated by the International Telecommunication Union.
A watchful eye
The navy implications for Chinese networks like Guowang and Qianfan aren’t misplaced on US Space Force leaders. Large megaconstellations like Starlink, or the long run Amazon Kuiper and Guowang techniques, have the benefit of being troublesome to disable or destroy, in comparison with a single giant communications satellite tv for pc offering wide-area protection.
“This simply is a continuation of what China’s been doing now for about 20 years,” mentioned Gen. Stephen Whiting, the highest basic at US Space Command. “In addition to all of the counter-space weapons they’ve constructed, they’re constructing functionality to allow their military, their navy, their air drive, their marines, to be extra deadly, extra exact, and extra far-ranging.”
“We’ve seen lots of of (surveillance) satellites, and now it looks like they’re launching this proliferated, low-Earth orbit constellation to provide them world communications to allow their operations on a broader scale,” Whiting mentioned. “Certainly, it is one thing we’ll be watching to see how that develops. But it is only a continuation of the breathtaking velocity at which they have been they have been shifting in house.”
Brig. Gen. Anthony Mastalir, commander of US Space Forces within the Indo-Pacific area, mentioned he’s most occupied with seeing how China integrates constellations like Guowang into their navy operations. China is conducting more and more “elaborate and complicated” navy workout routines, Mastalir mentioned, and US commanders will assess if, and the way, China incorporates the worldwide communications capabilities of Guowang into future workout routines.
“Seeing how they combine house throughout that train regime is one thing that we’ll be watching very intently when it comes to assessing the relative success of their megaconstellation,” Mastalir mentioned.

In response to questions from Ars ultimately week’s Spacepower Conference in Orlando, Florida, Whiting mentioned Space Command will monitor the deployment of the Chinese satellite tv for pc constellations, simply as they do different fleets, like Starlink. The distinction is SpaceX, with greater than 6,800 Starlink satellites at the moment in orbit, sends data on its launch schedules and spacecraft positions to Space Command, basically giving the navy a heads-up to know the place to look as they monitor orbital visitors. China doesn’t do the identical for its satellites.
Space Command at the moment screens round 47,000 objects in orbit, and screens them for dangers of collisions. If there’s going to be an in depth encounter between two lively satellites, Space Command informs their operators.
“When we see that there is going to be what we name a conjunction, we ship that data off, and we proceed to do this with China,” Whiting mentioned. “We don’t get common communications again. There have been a pair instances during the last yr the place they reached out via numerous methods to provide us heads-up about some issues happening in house, like a satellite tv for pc re-entering, however that’s not a routine, standardized approach of communication.”
Whiting mentioned he is not frightened concerning the security of so many megaconstellations coexisting in low-Earth orbit, supplied their operators “comply with tenants of accountable conduct.”
“We need to be sure that of us are doing all the precise issues with prediction, predictive conjunctions, after which not leaving particles in orbit, and all these form of issues,” Whiting mentioned.
But, nonetheless, Whiting mentioned it will be useful for Space Command to have a daily dialogue with China.
“We suppose there needs to be a technique to have house security discussions,” he mentioned.
