Ok, would the specific signal frequency, polarity, and embedded ID into the signal work for you? You keep trying so hard to misrepresent what is said to appear as if you are taking a moral high ground in a debate.
If you do not understand how microwave signals work, then stop speaking until you do get a little understanding. No the signal cannot come from multiple sources because it does have identifying attributes, couple that with how microwave transmissions propagate, aka LOS, and the fact that you cannot find a place where you have to point the dish in any direction other than the geostationary location. There are never 2 spots, there are no areas where you can't get the same signal strength as another towards a clear sky. The angle of intercept for the reflector. The knowledge and prior testing, by me as just one person, of how the LOS signal works at multiple, aka more than 4, different places separated by many hundreds of miles in the US alone. These are why talking about how known things like Sat communications cannot work on a FE model. Not at all. Please, come prepared if you wish to challenge further on how these work. I've got almost 8 years of practical in the field experience with sat coms, from TV to Internet to military systems. I'm not relying on what anyone told me, I tested things to better understand how the systems worked, so I would always know how to either ensure my customers had almost zero rain fade or me and my soldiers wouldn't lose vital coms in Iraq. I'm not a commo guy, I'm was a recon guy, scrape, scrounge, do for yourself because the help ain't out there with you.
But yeah, keep acting like it is possible to simulate 24/7 microwave band satellite communications with a bunch of balloons. It's laughable at best, it makes you sound d like a complete idiot at worst. I get what you want, but learn and try to understand things before you try to improperly use them failing to shame someone else.
...Getting mad is very rarely a useful response when someone's asking for clarification. When most of the time the reply is "They can just tell," - as others users have said before you - it's hard to not actually wonder. The problem is that this kind of justification is given significantly less often than this argument. Wanting people to do their own research is great, but there's a lot of sources out there which don't answer the question, and a wealth more that are just on search-term-similar topics. If I'm making an argument, I usually will - but asking someone to justify their own argument should not be a controversial thing to do. "There's an answer but we shouldn't need to give it," is a bad take.
Also, don't put words in my mouth. It's not 'I think this is possible,' it's 'Using signal triangulation is insufficient as an argument unless it follows that you can identify a shared source.' This isn't a challenge, this is a request for a
necessity if someone is going to try to make this point. Yes, you absolutely know more than I do on this subject, but if people want to argue against FE with this then a mere appeal to authority is going to be the opposite of persuasive. Ditto, it's not 'moral high ground,' it is 'There are certain things that are necessary for a logical implication to follow.' Like, especially on the post you're responding to. Do I get snippy with some users with dodgy histories? Yes, absolutely. No idea how the heck you get to that from "Maybe there's an answer, I just haven't seen anyone give it."
Next time, maybe don't spend the majority of your post getting mad at asking for the justifcation, and focus more on the actual question.
But, okay. What jumps out to me first is that 'embedded ID' feels like something that would be easy to duplicate? Even just hypothetically, is there anything that would prevent two transmitters claiming the same ID? Like, this was the first potential explanation that jumped out to me, and it doesn't seem to work by itself unless there's something unique going on.
Frequency and polarity, it's harder to work with, without applications given. I'm seen an argument made for attenuation before - which, again, runs into problems with respect to knowing the initial state, though it does get a potential out in regards to the rate of change with motion. Similarly, LOS seems like a lot of issues could at least be mitigated with regard to narrow-beam signals - though I agree, and did before, that the 'Is there a point where multiple transmitters are picked up?' idea, as JackBlack also said, is a significantly better response.
(The pedant in me is compelled to point out how that is standalone and doesn't require faffing around with the multitude of assumptions that triangulation requires, but it is certainly sound, if tested)
EchoStar 16 is leased by Dish Network to provide Direct To Home service.
Is it a lie that Dish Network is leasing EchoStar 16 from EchoStar where Echostar 16 is a geostationary satellite 22,000 miles above the equator located at 61.5° west longitude which was built to, and is broadcasting 24/7 programming to the continental USA?
No. That's true.
I hope the next question is going to be
why I think that. The justification kinda matters here.
