RE: 10 years from now... (was: internet futures)

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 permission to fly those objects in your airspace, I doubt 
that anything could be done about it.

If I owned a bunch of low orbit satellites costing millions of dollars each, I would not want to "park" them in low 
orbit over a hostile territory.

Then you also have the requirement to maintain positive control over the satellites which, unlike those in 
geostationary orbits, need to be under continual thrust and control in order to stay "parked".  I doubt that any 
"private" (ie, non-Government organization) could afford to do so without the cooperation of the state over which they 
are parking.

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 in a location with a very good, clear view of the
sky in all directions (even a single tree obstruction in one section of
the sky, relative to where the antenna is mounted will cause packet
loss/periodic issues on a starlink beta terminal right now). Visually
identifying the terminal would not be hard.


c) Portable spectrum analyzers capable of up to 30 GHz are not nearly as
expensive as they used to be. They also have much better GUIs and
visualization tools than what was available 6-10 years ago.


d) You could successfully train local law enforcement to use these sort
of portable spectrum analyzers in a one-day, 8-hour training course.


e) The equipment would have to be smuggled into the country

f) Many people such as in a location like Iran may lack access to a
standard payment system for the services (the percentage of Iranians with
access to buy things online with visa/mastercard/american express or
similar is quite low).



There are already plenty of places in the world where if you set up a
1.2, 1.8 or 2.4 meter C, Ku or Ka band VSAT terminal using some sort of
geostationary based services, without appropriate government "licenses",
men with guns will come to dismantle it and arrest you.

I am not saying it is an impossible problem to solve, but any system
intended for that sort of purpose would have to be designed for
circumvention, and not a consumer/COTS adaptation of an off the shelf
starlink terminal.

      This is what I hope will change in the next 10 years.  "Turning off
the
      internet" will be harder and harder for folks suppressing others,
many
      times violently, and hiding it from everyone else.  A small-ish
antenna
      easily hidden would be necessary.
