       | Seems like the NSA recommends a vpn to obscure VSAT use. They
       | don't have much else to say about anonymity.

       | EDIT 2: Found this thread:

       | After some thought, I think Starlink will be robust against
       | tracking. They should be harder to locate then VSATs which the
       | author mentions in the Twitter thread. In comparison:
       | 
       | 1. They are beaming to a constantly moving swarms of satellites
       | rather then a geostationary satellite: a. So timing attacks can't
       | be used to find a search path. b. The beam is moving to even he a
       | plane pickup on a signal it would quickly lose it as the beam
       | moved. Although there is a workaround I won't mention.
       | 
       | 2. They are lower powered so the signal is weaker. I assume they
       | are just as directional.
       | 
       | 3. They are smaller and harder to spot.
       | 
       | 4. They are much more numerous.
       | 
       | 5. They are portable.

           | - If they where clever they could time the latency and find
           | how far you are on relative to the satellite. Giving a circle
           | path to look at. Meaning plane could find you by flying along
           | the circle. So I guess it could help them track the radio
           | signal...

       | far as reasonably possible from yourself.
