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.
Would it actually go so far?
Would the police actually try to investigate from where came the jammer? Might the competing firm possibly even finance an investigation themselves privately? And if so, would the police then accept the evidence?
People have done far more evil things for money.
