I read the article, and unless I missed something, this is not a compass, which merely indicates direction. It is superior to GPS, which means it’s a complete navigation system with comparable output such as direction, speed, elevation, time etc.

The fact that it is self contained, that is not depending on satellites or another outside reference, does make it quite a gem if it is a accurate as they claim.

I did not notice if it is EMP proof.

All of those would be great aboard ship.

That’s the way it looks to me, too. It really should be compared to INS - which is probably what it really is. Seems like you could do that with perfect accelerometers, if you used a pair of them to measure angular acceleration in each of the three orthogonal axes as well as to measure linear acceleration in each axis.

But for such a system to outperform GPS, the quality of those accelerometers must be something to behold. Wonder if this thing needs an alignment time similar to that of an INS . . .

Little yet for the consumer version with all the eye-popping displays.

Guessing that it is close to an extremely accurate gyrocompass, that also knows where it has been, the rate of travel...

EMP proof? The guts (quantum accelerometer)probably.
For the support equipment, you may have wait for the mil-spec version.

And if you can hold out for the prosumer line...

You nailed it. Satellites can be attacked. if self contained..., if EMP proof... this could be a game changer.

Whether it is or not, if there ever is an EMP, you won't need a compass any more.........................
