Single element antennas, adaptive antennas, beam steering antennas. Basically attempting to pull good RF while avoiding bad RF. (this has been applied in the Russo-Ukrainian war in modified Starlink equipment) GPS antenna mods make Starlink terminal immune to jammers - https://news.ycombinator.com/item?id=39616417 https://news.ycombinator.com/item?id=39616417 - March 2024 (72 comments) https://olegkutkov.me/2023/11/07/connecting-external-gps-antenna-to-the-starlink-terminal/ https://olegkutkov.me/2023/11/07/connecting-external-gps-ant...

The Russian response to directional antennas is to mount GPS jammers on satellites https://www.gpsworld.com/todd-humphreys-russian-satellites-a-cause-of-gnss-jamming-across-europe/ https://www.gpsworld.com/todd-humphreys-russian-satellites-a...

  If Russia’s proof of concept moves to active use, those satellites (Kosmos 2546 and any others) will need to be removed from service with anti satellite technology (either munition or X-37B equivilent). Clearly Russia is attempting to shield an overt military capability behind the satellite’s early warning launch detection primary mission to dissuade attempts to disable it. Remove the orbital capability, deny them access to replace it. Ongoing Ukrainian strikes against Rassvet satellite production and launch sites contribute to further impairment of Russia's ability to get any new or replacement satellites to orbit. https://ua.news/en/war-vs-rf/video-ukrayina-atakuvala-golovnii-viiskovii-kosmodrom-rosiyi-plesetsk https://ua.news/en/war-vs-rf/video-ukrayina-atakuvala-golovn... https://en.wikipedia.org/wiki/Kosmos_2446 https://en.wikipedia.org/wiki/Kosmos_2446 https://arxiv.org/html/2606.03673v1 https://arxiv.org/html/2606.03673v1 https://www.youtube.com/watch?v=cRiOkQ1ngAM https://www.youtube.com/watch?v=cRiOkQ1ngAM
