China Gets on the Bandwagon To Provide Global Satellite Internet (qz.com) 86
Over the weekend, China launched a satellite into low-earth orbit, the first step of a plan to provide global satellite internet to people who still don't have reliable access. From a report: Nearly 3.8 billion people are unconnected to the internet, and women and rural poor are particularly affected. The satellite, called Hongyun-1, took off at China's national launching site Jiuquan Satellite Launch Center on Saturday (Dec. 22). Hongyun-1, or "rainbow cloud," is the first of 156 satellites of the same name developed by state-owned spacecraft maker China Aerospace Science and Industry Corporation (CASIC). CASIC intends to launch all the Hongyun satellites by around 2022 to form a constellation that will improve internet access in remote parts of China, and eventually in developing countries, a plan first announced in 2016. Most of the satellites will operate 1,000 kilometers (620 miles) above the earth, far lower than satellites are typically placed. The project is "moving the internet currently on the ground into the sky," said Hou Xiufeng, a spokesperson for CASIC, "It's China's first true low-orbit communication satellite... The launch will greatly boost commercial space."

Look at it this way - right now there are more than 52,000 merchant ships sailing the seas. Have we run out of space in the ocean? And then add in the fact that space is 3d, so adding in vertical stacks, the number of satellites that can be safely fit in LEO is huge.
Or for harder numbers, the earth has a surface area of 510 million km^2. Figure 1 km^2 area per satellite, and 1 km between orbital levels, and LEO orbits from say 600 km to 1000 km, and you get 204 billion satellites.
Sorry, this analysis totally misses
1) most ships and airplanes travel coordinated, non-intersecting, paths.
2) ships and airplanes also maneuver to avoid each other
3) while you have low density you also have very high sweep-rates
Neither is the case with satellites (although #1 might be possible), and we will soon see a need for such. The actual statistics on oritiabl collision with either other satellites or misc launch debris is already getting pretty grim.

Space is big but it's more complicated than that. One kilometer between satellites is only a little over 0.1 seconds in the direction they travel since LEO is ~7.8 km/s. You also can't just lay them in parallel like lanes on a freeway, the orbits looks like a sinusoidal [scienceabc.com] so the orbits intersect and get squished together at maximum inclination. Finally any satellites you're discarding must pass through the other orbital layers despite orbits intersection as you can't keep the exact same orbit from a different

So make a GNSS reciever that ignores any data from GPS satelites iand instead bases its calculationd on Galileo etc instead, presto no chance for the US to directly controll the input dara unless ofc the por in a call to ESa GSA and tell thrm to transmit bad data or else, but that is a different question and allso way ot.

I think you have it all wrong. People have no problem with the Chinese or their culture. The problem people have is with the Chinese government. You act as if you are unaware of their actions.
- they have been suppressing dissent and then hunting down dissidents to jail them
- the re-education prisons that they are putting Muslims into
- the massive video surveillance network they are building out

Obviously! There are no Chinese people in the Chinese government, military, not a single one is collecting a government check, or supports it in any way, right? Where do you suppose they are from? I am fascinated by this hard line that people draw between themselves and their government. I think it's to apply plausible deniability for what the government does, with full consent of theirs in the "west".

I look forward to well-reasoned arguments that are totally not Sinophobic and dog whistle racism, just like all the other threads that mention China.
It's not that I distrust the Chinese any more than other countries, it's just that I simply credit the Chinese with being capable of the same skulduggery as the US, European countries or Russia. So when I see them getting in on the ground level in the emerging LEO satellite internet industry and knowing that in China no company is really private, the Chinese government always has their fingers in everything to some degree, I have to ask: Is there a better way for the Chinese to do what they are seeing the N
