SpaceNewsTrustPoint sets 2027 target for initial rollout of LEO-based navigation services

@jt_rebelo @mastodonmigration @GottaLaff I'd call #Ukraine "criminally incompetent" if they didn't already leverage domestic #Fiber & #GSM networks as well as procuring entire transponders for exclusive use.
I couldn't confirm X-Band use with either #XTAR or #BwSATCOM-2 simply because I have neither teleport access nor matching LNBs/BUCs ready, but existing press releases by @Bundesregierung & @AuswaertigesAmt hint that Ukraine has been upgraded to #NATO #Link22 capabilities.
Existing #SIGINT & purchases show huge amounts of COTS #KuBand & #KaBand and even #Cband-Equipment being used since 2022, which use higher-ping #GSO|s but are easier to decoy and protect against #ElectronicWarfare and #Sabotage (just by shoving the dish into a partially buried sewage pipe, making it look like a ghettohacked Copy of #BARS, the Soviet-Era #Troposcatter CnC Radio...

@[email protected] @[email protected] @[email protected] @[email protected] as for #ITsec amd the whole #Starlink #Network: It basically uses a homegrown mix of #DOCSIS, #GSM and #ViaSat #SurfBeam technologies to generate these hexagon coverage areas. - Certainly not trivial, but not impossible to #BlueBox, tho unless one needs #FPS-grade #Ping|s, it's not worth the effort when other Options like #KaSAT are easier and cheaper to get hold of... https://infosec.space/@kkarhan/114048966406486263
@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.
#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.

@vwestlife #Funfact: In #Europe, #Cband dishes weren't common so #SatelliteInternet used simiar #Tuner cards with #VSAT terminals, usually accepting downlinks from regular commercial #TV #satellites that were just data channels on #ASTRA and/or #Eutelsat #HotBird in the #KuBand...
- Later they got some fancy "SAT-Routers" that combines a #DVB-S downlink and an #analog #56k / #ISDN modem for uplink if not offered to use #2G #mobile networks as well...
I've got one of those:
Basically a #Router with some #Linux on Ethernet, Power & F-Screw-Connector on the rear, #56k& #ISDN #Modem|s and USB up-front.
- And yes, I used that to share a #dialup connection with multiple devices, because they can do that!

ftgThis C-band LNB is a bit crusty. But might even work!
Should be usable for seeing 3.4GHz stuff on the spectrum analyzer, even if the DRO in this thing is not super stable.
Has anyone converted these to 5.7GHz?
The LO is 5150MHz
Shouldn't that just be ripping out or replacing some filters?
I wonder if it would upconvert with sane effort.
Gain is much cheaper and less fiddly on 3.4GHz and 5.7GHz than 10.3GHz.
Ian Littman#5G update: #TMobile has dropped 2.5 GHz (Band 41) #LTE entirely in a number of markets, including Austin, widening n41 by the same amount. I think the #Austin switchover happened at ~9:20am this morning as a friend briefly lost connectivity right around then (probably cell site reboot), prompting me to look at my phone's field test.
I found a sweet, sweet 100 + 80 MHz of #n41 live, which is well above what #Verizon or #att can bring online with #CBand right now.
750 Mbps indoors at home FTW!
Rob PegoraroBeing out of town from D.C. let me finally try out Verizon's #CBand 5G, and the results from near downtown Dallas on an Inseego hotspot were pretty good: 221 Mbps/34.7 Mbps. That's not as fast as T-Mobile 5G, but Vz's previous options were low-band "nationwide" 5G that wasn't much faster than 4G or exceedingly fast but exceedingly unavailable millimeter-wave 5G.
