@cleoabram: This tiny new device can navigate using quantum physics rather than GPS! Normally, a pilot needs four satellites to figure out its location…but this device uses atoms that act like compass needles sensitive to earth’s magnetic field, which is different everywhere! So it can record the magnetic “fingerprint” anywhere, no satellites needed! For more optimistic science and tech stories, follow along! #Science #magnet #GPS #quantum #technology

kalpana Konara :

isn't earth magentic field change slightly overtime?

5uper5hadowken :

It sounds like it would be able to handle more air traffic by an order of magnitude

Igor Lemes :

"Optimistic" lol this is clearly military tech for drones and missiles

Michael :

Spoiler alert: The main application for this technology is going to be hypersonic missiles and kamikaze drones… 💀

JerryJones2000 :

except Earth magnetic field moves and changes

𝔅𝔢𝔯𝔱 𝔖𝔦𝔫𝔤𝔢𝔩𝔰 🇳🇱 :

To bad the Earth's magnetic field is not a static thing. The North Pole wanders around.

MiooiM :

the precision of this thing can't be good.

polpol314314 :

3 satelites.......

👑 :

pilots don't need satellites to figure out where they are. There are devices on the ground that ping to them every x kilometers over battle tested flight paths.

Joel Petrow :

Correct me if I'm wrong, but doesn't inertial navigation already fill this need? it used to be used on spacecraft, airplanes, and subma, required strain guages and spinning gyrosccopes, be big, heavy and expensive. But now uses ring lasers, can fit on a chip or two, and is still used on subs and in underground mining where there's no GPS signal.

rr4pf1 :

This is so smart it makes my brain hurt

Law :

It’s called a quantum compass because it uses quantum atoms as ultra-precise magnetic sensors — but the navigation itself is classical, based on Earth’s magnetic field maps, not quantum mechanics replacing GPS!!!

rmp1405 :

drones and cruise missiles probably use this tech already

Guldkällan :

wdym optimistic news? All the video shows is a drone on its way to interrupt someone's childhood 😭

Phillip M :

won't replace GPs... but it works for other important measurements

RiBe44 :

Interesting how it is presented on a drone 😉

Jacob🏒⚛️ :

☪️ :

first

Trey | Runner ❌ :

More on this please 😊

Emi :

What is this called?

technologytechnol94 :

gps uses quantum physics 😂

[MnY]Guardian Kingshot 1931 :

can it give you depth location

Alberto Valis :

A drone like for an exemple.

brewp49 :

But the magnetic field changes and can change significantly in short periods of time so problems.

CaptObvious :

So it knows where it is by knowing where it isn't?
