@stardot @delta potentially.

  • Tho I do expect some classic mail push/fetch and local mailservers doing caching...

Just like in #McMurdo and #AmundsenScott, cuz #SATCOM via #TRDS (McMurdo) and #Iridium (#SouthPole) is expensive af...

  • So expensive in fact that people literally have to "get in line, take a number!" and depending the amount if data and priority of their comms they may be faster just grabbing an SSD, fill it up and send it back with the next plane...

Satcom Piracy

Last night I witnessed the HELL mode of communication being used by the pro-Ukraine satellite pirates on 245 MHz. The words read better when the waterfall scrolls up the page, so flipping the image makes it more readable! There was a variety of English and Cyrillic messages which were anti-Putin in nature.

Hellschreiber mode as a communications tool has been around since 1929 when it was invented by Rudolf Hell in Kiel (Germany).

@kallemp I didn't bother with #LoRa due to it being patented and #Meshtastic for tending to pollute #ISM spectrum.

Also #CEPT does have data channels on #CB radio that are allowed to be used.

  • Given the low duty cycle, I'd say it's worth using said #LicensingFree channels. Espechally since the only "regulated" part are transmitters and those are just transparent cheap boxes, so #AFSK will be fine.

OFC one could use this across any spectrum or means, ranging from WSJT - moonbouncing at extreme narrowband and high frequences to #UHFSATCOM radio piracy. Obviously I disrecommend the latter for legal reasons!

  • OFC one could also use it across i.e. #Iridium and other #SATCOM and regular #VHF & #UHF radios or even just print messages as QR-Codes...

With Lone Skum potentially pulling the plug on Starlink, politico.eu/article/eu-to-help I wonder how long it would take JP Aerospace jpaerospace.com/ascender175.ht to spin off an EU-based corp for high stratospheric comms platforms?

Surplus heavy freighters (DC-11s, 747s, Airbus Beluga STs, whatever is headed to The Boneyard) could also orbit at about 13 klicks up to serve as relays for a radius of about 480 klicks following Stratovision's model en.wikipedia.org/wiki/Stratovi #ukraine #starlink #satcom #EU #NATO

@amayer @mastodonmigration @GottaLaff NOT TRUE!

The entire CnC systems for #UAV|s by the US DoD use X-Band for video feeds and #Iridium for remote control.

  • In combat theaters, drones get either controlled by operators on the ground in visual range or get their targets directed by them i.e. via IR Laser Designators (so a Hellfire Rocket can home in!)

Basically no drone fielded supports #Starlink even as secondary payload because the angular velocity exceeds Starlink specs on existing terminals.

  • Most drones fielded by #Ukraine are close-range multicopters that drop mortar rounds vertically into trenches, they don't have any #SATCOM, they barely have a video feed on 5,8 GHz...

@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!

Continued thread

Issues aside it's now 15 years since I started using #Tor / @torproject & @guardianproject / #Orbot on #Android full-time.

Because in #EDGEland they yeet users to 64kBit/s if not even lower to 16kBit/s past paid bandwith and instead of properly renegotiating the bandwith, they trottle connections by reducing the packet rate / dropping packets, making it as #laggy as a #GSO-based #SATCOM connection!

  • On top of that, almost all #MNO|s & #MVNO|s illegally use RFC1918 Address space, *espechally 10.0.0.0/8 for #CGNAT, thus bricking #VPN|s and sadly @BNetzA doesn't really give a damn!

Why?

OFC since #Opera #Mini needs a trustworthy proxy backend any "#clone" would need an #OpenSource'd & #SelfHosting-capable #backend (similar to @ActionRetro 's #FrogFind .com as it breaks #E2EE.

Needless to say it would be a godsent for anyone stuck on #EDGEland and slower speeds (i.e. #SATCOM like #Iridium)...

@joshuafoust infavt, #SpaceX, (like the #Hyperloop,) is merely good ad #FUD'ding investments into #Infrastruvture like (#PublicTransport and) #Fiber, because even cheap-ass equipment cobbled together from fs.com can provide cheaper and faster connectivity in most cases by virtue of #FTTB / #FTTH being inherently faster, lower latency and cheaper to maintain...

  • Shure installing a fiber line may cost a bit, but like electrical and phone cables, they can be mounted on poles (aka. "aerial cable" amd aside from splicing and bending radii, have not that many concerns attached to them).

Plus fiber is way more energy-saving, fobust against #RainFade and doesn't rely on #proprietary & expensive #SATCOM hardware on the customers' ends...

  • Imagine how many kilometers of fiber could've been laid with the same budget, regardless if money, personnel hours or CO2 compared to launching megavonstellations that are so low in their orbits that they barely last years at best...

EUSPA is linking GOVSATCOM services with authorised government users📡

For fire brigades, police, military, coast guard and other authorised users, this pooling of secure #SatCom services means they won’t need to find and book them directly from the service providers – a process that could delay emergency response efforts. By always having some SatCom services reserved for EU Member States, GOVSATCOM reduces the risk of commercial services being unavailable.

www.euspa.europa.eu · GOVSATCOM, the EU secure satcom service hubWhen disaster strikes, having ready access to communications services is critical to emergency response and mitigation efforts. But what happens when a disaster, such as an earthquake, causes terrestrial networks to collapse, effectively shutting down communications within the disaster area? Or when the crisis area is located in the sea and there are limited or non-existent terrestrial communications networks? For this, there’s GOVSATCOM.

US NRO satellite from the NEMESIS program made a manoeuvre approaching a satellite used for French army communications, causing unease.
