    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.

      Edit: Please education yourself before you’re so confident in your own bullshit answer. https://gisgeography.com/trilateration-triangulation-gps/ and https://www.gps.gov/multimedia/tutorials/trilateration/

      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?
