A single satellite defines a sphere around itself (not just a circle—you exist in 3D space).
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.
Final Verdict
You’re not just wrong, you’re wrong AND you’re a dick about it.

Coordinates on a sphere is a 3 dimensional location. The earth isn’t flat.

Satellites broadcast a sphere, not a circle. And that sphere doesn’t land on the earth as a perfect circle for relatively obvious reason… since the ground isn’t perfect flat, nor is the earth perfectly spheroid.
The earth isn’t flat.
So which coordinate accounts for elevation? Latitude or Longitude?
Lat/Long is only valid if elevation is valid. You can’t reference a lat/long that is miles into space… or beneath the crust of the earth.
It’s like you’re making my point for me.
A watch… or other simple gps device doesn’t know what the elevation is.
Only one of the 2 selected points in a 3 satellite setup will be valid. And your device would have no idea which one is valid without elevation knowledge or a 4th satellite. Some devices can figure it out with just 3 satellites. Many/most won’t. But ultimately it’s the same thing. You need 4 pieces of input. Either 3 satellites AND elevation. Or 4 satellites.
So no. I’ve not made a point “for” you. You’re just ignorant or specifically being obtuse on something you clearly don’t understand.
A watch… or other simple gps device doesn’t know what the elevation is.
My point, exactly
Which is why they’d need 4 satellites. Read the whole post. Read the given sources. Stop being stupid.
I did read the whole post. Stop being an asshole.
