Which is much easier to generate/store on land than on space.
> RF signal falls away according to distance according to the inverse square law
On land, a state actor, operating on its own territory, could put jammers every 50 km, which is much closer to the receivers than satellites that orbit at 550 km. Even if the jammers transmitted at the same power as a Starlink sat, being 10x closer would mean jamming signal 100x stronger.
- peter_d_sherman 4y ago>being 10x closer would mean jamming signal 100x stronger. At a specific frequency. The effect is similar to how a nearer radio station at a given frequency -- will typically block out others that are at the same frequency, yet farther away... But does a strong radio station nearby mean that all other radio stations at all other radio frequencies are simultaneously blocked? No -- someone can simply turn the dial and tune in to a different radio frequency, and listen to another "unblocked" / "unjammed" station... If Starlink frequency hops, that is, automatically changes its frequency if bands of the RF spectrum are blocked -- then it will be much more difficult for the state actor to block all of them at the same time -- especially if each individual Starlink subscriber could frequency hop with no pre-set pattern, that is, independent of all of the others...
