Looks like with these frozen gasses one can build even better sensors, which will make no difference for civilian use because it will be even more expensive than existing systems and also because we wouldn't be allowed to use it.
If you’re a nuclear submarine or stealth bomber it makes loads of sense. For anything else I don’t really get the point.
Even just as a person, having a nav system that doesn't need to sync before it can be used would be nice, and no possible issues with buildings, trees, hills, etc.
If this works I can’t see a reason why in 10-15 year you won’t be able to fit it on a single chip.
It won't. It needs a starting position from an external source, and without periodic updates from some external source, errors will build up in this system just as with any inertial navigation system. As I understand it, this system is just supposed to build up errors much more slowly than existing inertial navigation systems, so it can go longer between updates from an external source before its error becomes too large to be acceptable.
If it's updated periodically what does that system look like? Is the advantage that it can manage on its own "offline" for a usable period, unlike GPS which needs an active connection?
And the published paper it refers to https://avs.scitation.org/doi/10.1116/5.0053885
And I agree that the answers to my questions are probably not public, this is likely going to be very useful for things that go boom, in addition to a lot of other civilian applications.
