Or maybe “Chinese fan boys” more and more of you wet dreamers are appearing on SDF bringing down the standard
Or you should read more than belittle others as "fan boys"?
Are you aware of the ongoing Jilin satellite constellation that is being constructed by China as we speak? Or you will call this American company "
" (doing/proposing same thing) as Fan boy?
Here are something for you to read
ONE of China's CIVILIAN project "Jilin constellation".
1. Some (not complete) count of operational sats.
2. Article in English
The Jilin-1 video constellation satellites each weigh around 95 Kilograms (1st generation) / 208 Kilograms (2nd generation) and measure 1.2 by 1.1 meters in size, hosting a camera system capable of achieving a ground resolution of 1.13 meters, covering a frame of 4.3 by 2.4 Kilometers. Imagery from the Jilin-1 constellation is offered on the commercial market and is hoped to find application in a number of areas such as forecasting and mitigation of natural disasters, resource exploration and various monitoring tasks.
With eight video satellites in orbit, Jilin-1 is halfway to its initial goal of a 16-satellite constellation to support a revisit time of four hours for any given target on the ground.
Expansion to sixteen constellation members is hoped to be complete by 2019 when the project will head into its second ambitious phase to push to a sixty-satellite constellation for global refresh rate of 30 minutes and the ultimate goal for the 2030 time frame will be a 138-satellite system with a revisit rate of ten minutes.
Summarize and update according to Chinese language sources:
- First phase by 2020, 60 satellites in orbit to reach less than 30 minutes revisit rate for any point of the global.
- Second (final) phase by 2030, 138 satellites in orbit to reach less than 10 minutes revisit of any point.
- Frame width is 19km today.
A US carrier's top speed is 30knots/56kmh. In 10 minutes it can travel at most 9.3km. It is still within the video frame of 19km of the next revisiting satellite. And it looks like this, and it is live video
Yes, that is 2030 with 138 sats. The minimum revisiting rate to keep a carrier in the frame of 19km is 56km*20/60=18.6 minutes. Most importantly, China does not need to revisit Antarctic that frequent as China doesn't care if USN went there. So China just need to put limited number of sats (60 by 2020) on orbits that covers Asia-Pacific to have a live show of USN ships. That is a reality in 2 years.
