Yeah, I agree that I didnt understand that bit. I also didn't understand why you need a quantum sensor to follow a map of gravitational and magnetic anomalies for orientation.

You don't. Any appropriately sensitive/accurate accelerometer or magnetometer is sufficient to do this.

The quantum part is 90% hype used to and attract funding. There are some advantages to the cold atom based sensors Q-CTRL makes, along with issues that need to be worked on, but they are other sensing technologies that could beat it in the long run.
