It still doesn't make sense to me. Long before GPS, in this country (Norway) you could buy ordinary orienteering maps where every stone could be located with centimeter precision. 1:5000 orienteering maps were generally available "everywhere" even in the 1970s, and if you go to the city administration to get a map the lot of your house, you'll get a 1:1000 scale map. You don't need to build a Glonass ground station for that.
Also: GPS is not giving coordinates as such; it is providing (very!) precisely timed signal. The receiver determines its position by comparing the timing of at least three different signals. A satellite could distort the coordinates by fouling up the timing of its signals, but then every receiver would read a distorted position, regardless of his coordinates. You cannot foul up the timing for only a few selected coordinates.
I very much doubt that the Russians did not have a quite precise map of the entire US long before Glonass was put into operation. They've had a space program since Sputnik 1, and properly placing Glonass satellites in space is not a task done with steel wire and duct tape. They do have quite sophisticated technology, whether we like it or not. There is no reason to believe that they need a handful of ground stations in the US of A to learn where it it is located  . Not today, and not when GLONASS was established.

To the best of my knowledge maps are intentionally not precise when it comes to strategic locations (including Cities). And few meters off is quite enough to throw off targeting systems based on coordinates (or your car GPS locator). This could be corrected using satellites, but the russian qeo-imaging/Synthetic-aperture satellites are garbage - IIRC with resolution as low as 400 meters. So, they need those stations to pinpoint certain buildings\objects and for dynamic targeting.

Not 100% about Beidu, but Glonass wouldn't even remotely work in the USA to begin with. They have problems even covering the whole of the former USSR or any significant part of Western Europe.

at first using some top GPS status app, only saw the China one?
then tried GPSTest gave me US of A one.
then 5 minutes later, showed China
and 5 minutes more, as about to write up that on google phone 6, only USA and China, and then European one started
relieved, thought was in some dabger bubble

With the satellites moving at quite high speed across the sky, them coming and going is expected. Signal strength varies from second to second with varying conditions in the upper atmosphere (ionosphere). If you are indoors, signals are usually significantly weaker, and may change e.g. when a person walks across the floor above you.
Picking up BeiDou only (for a short period of time) may be somewhat surprising, but may be a combination of random events and e.g. that the GNSS tuner in your smartphone may be slightly more sensitive to the BeiDou frequencies than the GPS ones, or that the ionosphere affected the frequencies differently. Or that your phone, when you turn the GNSS logic on, looks for satellites in a given order, BeiDou before GPS before Galileo.

Well, my new PC sure looks pretty, but it doesn't do anything. I've tried about 67 times to install Windows 11 and nothing works. It took a while to work out the compatibility issues, but the BIOS configuration was right a few days ago. Now it will boot into the Win11 Setup program, but it won't get past the point where it's at the 4 - 5% spot of "Preparing files for installation." It crashes with the error: "0x80070570" which happens to mean anything Microsoft wants it to mean. I thought it might be a defective DVD media, but after more than 20 attempts to get that to work, I tried the download approach to make a bootable USB Drive. That causes the same error, at the same point in the setup process. I'm at wit's end with this POS.
I've assembled a lot of PC's in the past 30 years, for myself and for others. I've never experienced a single glitch, as everything has always gone perfectly smoothly. But I've never used an ASUS motherboard. I will never do so again.

Have you tried this?
SetupDiag - Windows Deployment | Microsoft Learn[^]
I haven't, but it might help diagnose. After that, you are down to MS Tech Support I guess.
They were pretty good last time I needed them.

The last time I was able to get through to Microsoft Support, it was because I couldn't get disk 13 of 13 for Windows 95 to finish loading. Three hours later the tech agreed to send me a replacement. Last night I managed to get through to them, but their server failure routed me to the Office support desk. He was very kind and helpful, but out of his depth, so he sent me instructions on how to initiate a chat next week. I had to laugh; if it ain't broke, it ain't Microsoft. Even their internal systems don't work.

I feel for you I really do. It's the old thing "I have done this a thousand times, what am I getting wrong, its the industry satandard". This week I have been playing with a Servo motor trying to build it to a test platform for a subassembly. Monday to Wednesday nothing wouldn't start reliably and did a full 380 turn, Thursday and ultra sound machine failed all hand on deck to fix it. Friday back to Servo check the data-sheet for thousand time, notice three gramatical errors and two spelling mistakes, think 'might as well' swap over the data out and data in lines dang thing starts working.

Dancing and drinking is definitely on my agenda - thanks for the tip. I'm walking away from this nightmare for the weekend and will deal with it another day.

I suggest booting a Linux live CD/USB stick and doing some analysis on the hardware.

Not a bad idea! Coincidentally, I just downloaded an Ubuntu distro and have been toying with installing it on one or the other of my machines.

Might be able to mount the Windows drive (if it got that far) and access the installer logs.

Nope. There is no Windows drive. It stops at 4% Preparing Files - it never does anything to the drive.

I would never buy a new PC, expecting to "upgrade" the OS on it. I would only buy with the desired OS "pre-installed". Unless I was building from scratch.

Since I've never bought a prebuilt PC since 1994, that's exactly what I'm doing - build from scratch.

Replace the motherboard?
(My mistake: when someone says "new PC", I assume off the shelf; I just refer to my "latest creation")

That's certainly a possibility, Gerry, but not until I'm convinced that it's faulty. The odds of bad RAM are far higher than a bad MB. Oh well, it will eventually become obvious what's wrong.

Have you considered that you might have a bad memory module? Did you make certain that the RAM you installed is on the compatibility list of the motherboard?
I have always used Asus motherboards with great success.

It's possible, Richard, but I've no reliable way to test it. The motherboard BIOS setup includes MEMTEST86, but the results are inconclusive. It bails out and fails while running, but the summary results say PASS: 100%. Go figure. There are other memory test utilities out there, but they all assume an operating system is there to execute them. I do have a fresh copy of Ubuntu that I can try, I guess.

Yes, the Ubuntu sounds like a very good thing to try. I had the same problem with a machine that I built in 2015. It wouldn't load Windows and the problem turned out to be the RAM was not compatible with the motherboard. That's something very important to be aware of.

Curiously, I used the PC Builder system at Newegg to select components, and it supposedly checks compatibility. But then I did do all my own checking just in case.

Hiren's stopped the work a while ago, but there is another new DVD of it for PC's from windows 10 times.
It might bring a couple of tools inside helpfull for the new hardware.
M.D.V. 
If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
Rating helpful answers is nice, but saying thanks can be even nicer.

There is many ways to check, you can use the Windows Memory Test Point 9 here , you can make your own bootable memtest86+ stick (download UEFI or MBR boot): MemTest86 - Download now!, or use Hiren's BootCD 15.2 Download | TechSpot.
Maybe checking that the RAM runs on the specs in the motherboard helps, my Kingston Fury RAMs did not start with the last two AMD boards (Asus, Asrock), had to manually set the frequency (lucky me, nothing beyond that). It was auto-recognized as a much slower RAM with different timing.

The MemTest86 UEFI boot stick did the trick. I've isolated it to one pair of memory sticks, but can't sort it out beyond that. Sadly, since I've never had a failure before, I didn't keep the original packaging, so I can't return those two. Oh well, I suppose 32 GB will do for now. Thanks for the tip!
