Indeed.
>The system deduces the strength of Earth’s gravity in every given point of the journey from the motion of the atoms illuminated by laser beams inside a vacuum chamber and compares that data with gravity maps compiled from satellite measurements.
- arethuza 1y agoIs that like TERCOM but using strength of gravity rather than terrain height?
- i_am_proteus 1y agoPrecisely.
- kklisura 1y agoYup, I was just about to comment the same. I find it shocking that there's enough information/variation in gravitational field that you can match on.
- adrian_b 1y agoThe variation is very small, and that is why it can be exploited only with an extraordinarily sensitive gravimeter, like the one discussed in the article.
- actionfromafar 1y agoVery Star Trek technobabble vibes, except for real!
