@mastodonmigration @GottaLaff Obviously, all #SATCOM is insecure.

  • X-Band - based #MILSATCOM use proprietary encryption systems.

  • The best in terms of #COTS AFAIK is #IridiumPTT which does #AES256 over the air (if not the entire #IridiumNext system except legacy services) but that is a fully-managed solution with custom, embedded hardware.

  • Whereas most commercial satellite Internet is insecure af, tho I'm shure Ukrainians know how to setup their own #VPN!

@mastodonmigration @GottaLaff noone relies solely on #Starlink, espechally given it's big-ass dishes.

  • Even the #US #DoD uses #Iridium & #UHFSATCOM.

  • #SES & #Eutelsat have various commercial #Cband, #KuBand & #KaBand transponders for bidirectional data from their GSOs.

  • #XTAR has a #Xband-Spotbeam.

  • #Ukraine has both #Fiber and #Radio links (civilian and military) to link together units and emplacements. Espechally direct-burial/lie-flat fiber is used because #COTS parts are cheap, commonplace and unlike copper, they can do 160km+ without amplifiers with ample of room for splices.

Pretty shure Starlink was a mere "comfort feature" allowing units to send their drone footage from their FOB to HQ for instant #Meme|fication and "scoreboard updates" but I'm shure worst-case the #NAFO friends will just pack in some 2,5" SSDs and USB cases with the next supply trucks or have some #Skyhook-Style delivery system if that was ever needed.

  • I'm shure the folks in the trenches will miss YouTubing in their toilet break, but I'm shure they still have enough #Memes and #Entertainment in reserve to compensate for it.

I have not looked into this for quite a while so I have no definitive suggestion here, just brain storming.

I had been looking into geographically dispersed replicated storage. Those not deeply techically inclined could use #COTS storage such as #QNAP or something else. This is not an endorsement that was just a name that I remembered at this instant. More technical could use homebrew R-Pi or some other #OpenSource solution. A limited number of people could

Kleinsatelliten: Leistungsfähiges Datenmanagement im Orbit
"
"Erdbeobachtungssatelliten sammeln große Datenmengen, während die Übertragungskapazitäten zur Erde begrenzt sind. Spezielle Computer, sogenannte Data Processing Units (DPUs), speichern, werten und komprimieren diese Daten direkt im Satelliten – effizient und zuverlässig."
