My guess would be scientific experiments where they need to correlate or sequence data over large regions. Things like correlating gravitational waves with radio signals and gamma ray bursts.

those are GPS based too. You typically would have a circuit you trained off off 1PPS and hopefully had a 10 or so satellites in view.
You can get 50ns with this. Of course, you would verify at NIST.

I believe you'll need 12 GPS sats in view to gain incremental accuracy improvement over 8.
GPS could be blocked easily, and AFAIK even given corrupted inputs. And HFT could possibly benefit from blocking or corrupting competitors GPS.
Deploying a GPS jammer in civilized territory is a great way to go to prison.
