FCC chair says we’re too dependent on GPS and wants to explore ‘alternatives’.

Is that the difference between when something like Google Maps has your general location and when it has your specific location?
A-GPS works faster than GPS on its own.

You keep asserting false statements that have already been disproven with sources.
I don't. You just aren't paying attention to what I'm saying. You keep arguing up a strawman.
You are not getting a 3 dimensional location. That’s why GPS coordinates only exist on 2 planes. You don’t know what you’re talking about.
Proven wrong, as it's a "2d" map that only exists on a 3d plane. It's a slice of space that represents the moving target of "ground level". The point that this is a problem to take it as just a "2d map" is that you can't take 3 point readings from on top of a 1000 ft cliff and 3 feet away at the bottom of a cliff and expect 3 point measurements to actually give you accurate measurements since it's just "2d" right? Elevation matters as it needs to be accounted for during the calculations.
So which coordinate accounts for elevation? Latitude or Longitude?
Where elevation = ground. As stated...
Then you assert.
It’s like you’re making my point for me.
Which was in response to a post stating that the watch would need a 4th satellite or "elevation" in order to get a valid GPS value.
And after I further clarified for you how it works... again... and that I was NOT making your point. I assumed you simply didn't understand the point I was actually making.
My point, exactly
No... It wasn't your point at all because you asserted that GPS is 3 point triangulation. When it's 4 point Trilateration which only has the option of 3 point when the fourth value of elevation is already known, which the vast majority of devices that use GPS don't know.
What have I straw-manned? Can you point to it? What part of GPS needs 4 nodes/data points is vague?

Reject modernity, return to sextant.
Dont need a sextant if you dont leave your house

They're already are multiple alternatives to GPS. GPS is the American navigation system, but there's also GNSS which is mostly used in Europe and Scandinavia. There are other systems for other parts of the world, even the North and South pole now.
Everyone just uses GPS universally though.

You know what's a great backup? The ability to read a map or use a compass. This is set up to get Starlink or another billionaire to own GPS.
Subscription based navigation? Want to use your car's navigation system, there's a fee for that? Want to fly a drone, that'll be 9.99/month. Hopefully there will be a carve out for emergency systems.
This will also allow Tesla to up their traffic game. If everyone is using the Starlink GPS for navigation they'll have all the data.

GNSS is the generic term that covers all satellite navigation systems (GPS included).
Galileo is the EU/ESA system you're thinking of.
GLONASS (Russian) and BeiDou (Chinese) are the other two major constellations with global coverage. The only other full system I know of is NavIC, which is Indian and has only regional coverage.
Most devices actually connect to all of them. I've just checked my phone, and it's connected to all of GPS, Galileo, GLONASS and BeiDou. People just say "GPS" because it's catchier than "GNSS".

I kinda like the British word "satnav".

Why not just stop being reliant on cars... you know... put down more rail.... use.. trains...

Is constellation the actual term for a set of satellites now?
