But what was the attack and the change?
- notpachet 5y agoProbably much more banal than the article leads us to believe. Russia probably began jamming on <frequency x>, Starlink deployed a change to fail over the terminals to broadcast on <frequency y>. Would be my guess.
- Symmetry 5y agoProbably a bit more sophisticated than that involving patterns of frequency changing at certain intervals, but essentially.
- stefan_ 5y agoMy naive assumption was that since the Starlink terminals use phased arrays for beamforming, they were much less susceptible to brute force frequency jamming to begin with. Is there some truth to that?
- simne 5y agoAs I understand, it is prohibitively hard to make constant signal with high enough power, so SL will not work. So usually made trick - EW find when sync should be, and emit short high energy impulses, so snr become too low to receive sync part, and transmission effectively blocked. Spacex implemented new encoding, where sync is in random place in time-frequency, so now EW could emit, and this will lead to speed degradation, but not to full blocking.
