They overcame the jamming because the antennas are phased arrays with tight beams and low sidelobes. They updated the software to put a beam null point everywhere a jamming signals showed up thus rendering it null. That was at the satellites in the uplink side the down links are already fast moving tight beams and the ground terminals only track a tiny spot in the sky where the satellite is expected to be. To jam a ground terminal you have to position your jammer along that beam line then keep up with it’s movement across the sky at 7+ miles per second nearly impossible. The secret sauce is in the beam forming at the phased arrays of those birds once you have active null control they become very difficult to jam. I would expect the up and down links to also be frequency agile to some extent as well since spacex was given a block of bandwidth.
Sounds reasonable, thanks
Generating a beam null point whenever it detects a jam in real-time sounds like a lot for a SW update to do
Is your assessment on Starlinks workaround based on a known report, speculation, conjecture? Any links available?
