Satellites project a sphere, you need 4 in order to get to a singular point. I’ve outlined each step. Fourth isn’t for clock correction only. And even outlined why sometimes 3 is okay, but that requires additional logic that many gps devices sometimes can’t compute, and even outlined that the vast majority of devices will use way more than 4.
No.

Edit: The images on the site depict the exact thing I’ve been referencing.
1 satellite = whole sphere of options.
2 satellites = a whole circle of options
3 = 2 points
4 = 1 point.
