[@bramcoteelectrical1088]

They know exactly where that plane is😊. Think rolls Royce and data from engines sent all the time... Oil pressure Temps etc. 😮 The engines I heard were technically rented inside the airframe so rolls Royce know every point that he plane is. Maybe you guys know the protocol that data is sent by? I think i read the rolls Royce data thing sending on a plane forum few years back 😊

[@mrw1160]

Wild stuff, I appreciate learning how the UK uses their radios they really say a lot we don't here in the states lol

[@EvDelen]

8:38 By definition there wouldn't be anything on the tower, it's a passive system that would use the existing emission as a radio source while the proprietary CELLDAR portable station would be use the reflections of that radio source off of the tracked object to produce something analogous to RADAR. It's kind of clever actually. All you need to know is the precise position and azimuth of the emitter, which you can access off of public filings, and some trigonometry. It would be particularly useful in an adversarial military situation. This may account for some of the concerns that governments have has around certain countries mobile phone infrastructure, since it *could* be repurposed like this.

[@BlauJen887]

That sets the Huawei responses into perspective, perhaps.

[@HA05GER]

​@@BlauJen887 I mean Huawei never completely left so if the Chinese wanted in they could. For example alot of broadband suppliers used Huawei routers, alot of open reach fibre to the premises equipment is Huawei, Huawei phones are still in use and honour, who were part of the Huawei group but are now separate but still owned by the Chinese government, still selling phones here I literally bought one very cheaply yesterday while my phone goes for repair. That's just the stuff I am aware with but likely they have chips in all kinds of equipment. If the Chinese wanted anything they already have it. If people can hack military systems then I'm sure someone could use Huawei equipment to get Into our infrastructure.

[@RobWhittlestone]

Great video, Lewis! Roke Manor Research has done some really excellent work. At one point in time they had an excellent clock for precision timing (I think sub nanosecond) using TDOA method for multilateration emitter location systems. If I remember correctly it was sold to Indra Sistemas. The more precise the clock, the higher the precision of location. Light (and radio waves) travel 30cm in a nanosecond. When combining results from multiple sensors in 3D an aim may be to achieve 1m precision so the smaller the error of the individual sensors, the better the precision of the combined result. All the best, Rob in Switzerland

[@goiterlanternbase]

I heard of the paper this is based on and never heard those algorithms where implemented👍 This system works for all targets, as long as enough cellphones are around. So the target doesn't need an cellphone themself😎

[@A.R.O.T.A.]

If you have a smartphone it probably has Google Maps pre installed and is normally set for satellite location tracking plus cell tower tracking to improve accuracy while Google isn't interested in who you are the same system could be used to pinpoint a specific phones location and movement speed and direction. Other GPS systems also access the same systems to improve accuracy and even gauge traffic flow etc. Motorcyclists also use a sudden stop system built into their phones to indicate a crash and make emergency calls in case they are unconscious.

[@anchopanchorancho]

Makes me wonder if the data is encrypted when transmitted or if everyone's GPS data is broadcast in the open.

[@TheOneTrueDragonKing]

Good points, and you're exactly right. I think this program would have been perfect for global surveillance, however I do think it could have been abused by less-savory nations that we don't want to have this sort of technology.

[@irreverend_]

Don't forget that Google also uses WiFi APs to improve location accuracy, since the street view vans also make a log of which MAC addresses are in range and their signal strength. I think people's phones also update their records when you have a GPS lock.

[@thebrowns5337]

Edward Snowden recomends turning as much stuff off as possible and removing your SIM unless you need to make contact. He's at the extreme end of course but he also has some actual lnowledge of who knows what. And it's not just phones we invading our privacy. Remember 'smart' TV's listen. Cars with connection for emergencies or OTA updates also send location and can listen. There are dash cams that face both ways, have GPS and mics and their apps allow the cars owner to see video feed, hear sound and see positional/speed data. Nest smoke alarms have microphones. Teslas have 9 cameras for their 'sentry mode' but, as they are part of Musks empire (yes, he of 'X' - that even if you don't have an account can track your internet use providing the sites you visit have an 'X in' somewhere), lets just assume they are mobile CCTV stations and seeing as though Zuckerberg has his glasses out in the open, proven to allow facial recogniton (there are some creepy videos of how quick you can pull up the life history of starngers just by looking at them, all data handed to you on the HUD), we need to assume Elon has also allowed facial recogniton on his cars. We have lost almost all privacy. And people mostly lap it up. It can make life easier or more fun in certain circumstances (apparently) but when a wrong'un comes into power and realises what they can do... it'll be too late. oh, and lets not forget the social media apps, such as whatsapp and tiktok, that encourage people to take selfies and apply filters... have you seen the grids they use? - exactly the same as facial recogniton software uses. So people, especially children, are scanning their faces for these companies. Insane.

[@Katashtrophie]

First I've heard of this ever happening ..... However I've thought for a while that the push for 5G had an ulterior motive and that a "celldar" system was that motive. From what I've read about the frequency that a 5G mast is capable of its similar to a military radar system.

[@StreakyP]

As you said interest in passive bistatic radar has been around for years & mobile phones is no exception however the TDD (time delay duplex) on modern systems where base and user transmit on the same frequency (and the beam steering & frequency reuse) makes the DSP needed to get it to work much more complex. Anything with a repetitive signal can be used for bistatic passive radar, the Frame pulse on old analogue TV was ideal for this and during the cold war before the Berlin wall came down there was interest in slapping a receiver on a roof in west Berlin (or any other embassies elsewhere) to listen to reflections of the big Berlin TV transmitter to have an aircraft watching radar deep in enemy territory. Going back in history one of the earliest successful passive bistatic radars was Der Klein Heidelberg parasit which was a ww2 German receiving system that actually used our British chain home radar pulses against us (called the parasite as it fed off our system)

They were tracked well resulting of a half dozen arrests . At times it feels too much big brother here out here in the sticks we have them too sad it’s gotten that way .

[@stevesmith7530]

Hardly a new concept, the original tests for radar involved no specific transmitter, but listening for a BBC radio signal bounced back by the target. Similar has been experimented on using wifi routers too for very close range mapping and tracking. Funny really, death rays became radar, and now "deadly" cell signals have become radar too. The more things change, the more they stay the same.

[@alastairbarkley6572]

I don't think your 'all radar is radar' argument is convincing. Can you really compare the crude 'proof of concept' mid-1930s stuff in a car boot experiment with the digital, software driven, distributed reception system described here? Watson-Watt's system was only 'static' because it lacked the resources to generate 'aperture'.

I think it would be useful for mass surveillance of rural or generally un-occupied areas, the output from such an automated system could be used direct additional scrutiny by other means that need more human effort.

[@David0lyle]

Well there might have been another effect. See fisherman and other boaters have noted that the cellar phones range when contacting shore has been declining year over year for quite some time. 🤔 What’s been happening is that as the numbers of phones have increased the number of towers has increased and the cells have gotten smaller. 🤷‍♂️ I can’t say for certain that this would make the technology unusable but I would strongly suspect that implementation would become substantially more complex. Bounced signals would get weaker and would have to be sorted out from a more complicated soup of signals at differing power levels and directions. It doesn’t sound like something a computer could not do but it doesn’t sound particularly simple or easy. 💁 That said, what would not be particularly difficult to do would be to track the actual transmissions of the phones themselves. As long as the subject is willingly carrying a transmitter it’s no particular trick to track that and sorting that signal from background would be simple. Not so long ago students who vandalized a Highschool at night were easily identified by the automatic logins that their cellphones made on the schools WiFi . 🤦‍♂️

[@rogerlafrance6355]

radar does no identify the target whereas cell systems calculate the location of a phone to decide which tower to use and hand off to. your phone is always answering pings from the towers. This info can be used to track you or count how many cars are at a stop lite, folks call it GPS but its not, just measures time between two or more towers and you can only be in one place with those times.

[@RingwayManchester]

The radar itself doesn’t identify the target no but the software behind the system can to some degree

[@earlyadapter643]

Thanks for the good video. Sorry i also don't know about the longterm outcome of it. The Doppler charts remind a bit of meteor scatter that the SDR people can see, i think you mentioned it as astronomic particle. The advantage of using more and smaller transmitters rather than the one big DVB-T station might be more accurate altitude information because of the larger elevation angle (as there is always a cell tower underneath the object not too far away) and more triangulations.

[@joetheox1202]

The long-term outcome is the people will revolt. Eventually.

[@earlyadapter643]

It depends. Passive radar is quite stealth so chances are it goes unnoticed, and the applications are dual use as for many technologies so not everybody may be opposed to detecting enemy missiles.

Worries of ‘big brother’ mass surveillance always need to be considered against the context of the financing, backend data processing/storage requirements and project management capabilities. I’ve serious doubts they would likely not even come close to financing, let alone organising complete deployment. …they can’t even successfully project manage many IT system deployments from the likes of Crapita and Fujitscrew. The deployment of any technology is subject to cost vs benefit and the reality is the government couldn’t care less about the average citizens movements for the exponential increased cost and complexometer score that mass surveillance would require. It’s not to say that deployment of a Celldar systems doesn’t exist in places and if so most likely is specifically targeted around certain places…like that Andy Kirby’s house 😂
