The present architecture is logically a bent pipe, where a moving satellite (preferably more than one, for make before break handoff function) needs to be simultaneously in view of a starlink earth station and the CPE. In the long term this may not be an absolute. Ten beta test satellites that wer

By definition and orbital mechanics, low earth orbit things don't "park" anywhere. There's an equal number of starlink satellites over Mongolia right now as there are over the same latitude locations in the US and Canada. https://satellitemap.space/ This also becomes intuitive once one plays Kerb

Net to mention, of course, that the Low Orbit constellation would need to be "parked" over China (or where-ever you want to access it). I am quite sure that "shooting down" such low orbit stationary vehicles would not be too difficult. And if they are owned by an adversary who has no permiss

This is a fascinating discussion. Also keep in mind that starlink satellites need many earth stations to downlink customer packets and provide internet transit. There are over 50 satellite earth stations in the US already. Here is a great google map of the current ground stations based on FCC

No need for all that fancy RF tools. Moreover, detecting >10Ghz transmission is not such an easy task. The beam is most likely narrow enough to be difficult to detect. But, (for example) it's enough to visit from foreign IPs some local website, to have cookie set: SATELLITE_USER=xyz Then when p

I would also concur that the likelihood of Starlink (or a Oneweb, or Kuiper) terminal being used successfully to bypass the GFW or similar serious Internet censorship, in an authoritarian environment, is probably low. This is because: a) It has to transmit in known bands. b) It has to be located
