Too often, the vertical location (Z-axis) information that 911 call centers receive is not easily usable

So...use the barometer in tandem with GPS? This is shit I can easily track from my personal Homassistant server.

Also, you know how to make GPS more reliable, secure, and redundant? You launch more GPS satellites.

But where will we find room for more Starlink satellites if we do that? Elon said he needs another contract, and when the boss says jump...!

Starlink is LEO, GPS is not.

And I'm sure that's a distinction politicians really care about. /s

Your answer is rational. US politicians are not, since they have an agenda to hand off their money and power to Trump and Elon.

One can use both and anything else frankly, isn't it enough to triangulate the signal between 3 satellites (or 2 with an interval and knowing their trajectories relative to each other) and match the spot on the geoid's (stored model, position precalculated by time) surface?
