Quantum-assured magnetic navigation with higher positioning accuracy than GPS
- kavalg 2y agoThe abstract doesn't mention that accuracy is better than GPS, but by INS (inertial).
- daveguy 2y agoIt is not better than GPS. It is better than traditional inertial navigation systems (INS). But the accuracy is sub 500m for a good portion of operations vs multi-km resolution for traditional inertial systems. The title should be changed.
- Tor3 2y agoYep, the title is completely wrong. The actual article says ".. INS", not GPS. It can't compare with GPS to begin with. From the article: "the best final positioning accuracy we achieve is 22m". GPS can be accurate to a centimeter level, even inaccurate (no other reference) GPS is at least accurate to about ten meters.
- rocqua 2y agoFor plenty of military applications, 90m accuracy is a valuable fallback in a GPS denied environment. It's probably not nice for targetting purposes. But for general orientiering and the question 'are friendlies in this area' it's a lot better than nothing.
- kevin_thibedeau 2y agoMX with inertial guidance had a CEP of 90m.
- defgeneric 2y agoThis also omits how often the area needs to be resurveyed. Could be yearly, which isn't bad, but that could limit some applications.

- croes 2y agoCopy & Paste error, the "alternative" is missing from the title
- defgeneric 2y agoThis has been possible for some time, and there is an open implementation here: https://quantumvillage.org/ https://quantumvillage.org/.
