NFL. Ukraine military is really smart. It will be a blow to lose Starlink, but they have certainly established contingency plans for this eventuality.

@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.

@kkarhan @GottaLaff

NFL. Seems like they would be foolish to imagine Starlink to be secure as well. Certainly nothing critical could be trusted on the network.

@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 [www.youtube.com], tho I'm shure Ukrainians know how to setup their own #VPN!

@kkarhan @mastodonmigration @GottaLaff

Trust no network, not even your own.

@admin @kkarhan Trusting the network run by a guy who has arm spasms reminiscent of the Third Reich would be... unwise. Full encryption on it, and realize your dish location will be transmitted to whoever wants it.

@ai6yr @admin OFC it's trivial to find a transmitter when it transmits.

• Which is why Ukrainians hide their dishes well [infosec.space] inside buildings and away from the actual troops...

Also critical comms still uses #analog #PTT #Radios where only the transmitter can be detected during transmission, so troops can be commanded & warned without putting them at risk.

• OFC they gonna transparently encode & encrypt stuff but the ISM Bands & CB-Band is lit af...

@kkarhan @ai6yr
From what I've seen and been told, the go to radio for the UA is a Motorola HT or mobile using AES256 encrypted DMR. You can get an off-brand chinesium version DMR HT for under $100USD. (TYT MD390UV)

@admin @ai6yr Again, that's one of the tactical radios in use.

I know old German PTTs like the FuG 7b got handed over - freshly decomissioned after EMS & Fire Departments went fully digital (TETRA) in Germany.

@kkarhan @ai6yr

By PTT, do you mean a handheld radio? They are called HTs, for Handie-Talkies™ from the Motorola classic marketing name for them. PTT means Push-To-Talk, which is non-specific.
In some circles the term is more correctly RTL, or Release-To-Listen.

@admin @ai6yr yeah, abeit the old FuG 7b isn't really handy: It's about the size of a Cigar Box and weights about a kilo with a huge-ass NiCd - Battery screwed on the bottom.

• Granted, it's 1970s tech...

@kkarhan @ai6yr Here's two UA soldiers with XPR7550e HTs.

@kkarhan @ai6yr
While the invaders use cheap $10 radios from Alibaba.

@admin @kkarhan BF-888S, LOL.

@kkarhan @ai6yr

Last night I ordered up two MD-UV390s with OpenGD77 to run as hotspots. https://letsgetreadyinc.com/opengd390plus
