They performed two kind of measurements. On a bench they measured the drift of the helium-flow gyroscope in itself, and then they took the whole system to drive test loops and measured the errors in eastings and northings.
Quite a thorough job in fact, but I guess that is what you get if you ask a rocket scientist to evaluate a new-fangled vehicle navigation tool.

- analognoise 4y agoI'll bet HNers have a collection of fascinating subreddits. HN is better - it's broader and there's usually amazing takes in the comments (amazing good, not YouTube "amazingly WTF" style comments)
- machinehum 4y agoThanks for the link to the paper, this was an insane amount of work.
