3:30 A fibre-optic gyroscope (FOG) senses changes in orientation using the Sagnac effect, thus performing the function of a mechanical gyroscope. However its principle of operation is instead based on the interference of light which has passed through a coil of optical fibre, which can be as long as 5 kilometre. The Sagnac effect is used in optical gyroscopes by sending two beams of light in opposite directions in a fibre optic coil or mirror directed path. As the device rotates, the beam travelling against the direction of rotation experiences a slightly shorter path delay than the other beam.
The French have always been known for being at the top of inertial navigation systems. Their products are used worldwide, while no single company in the Anglo sphere comes even close. As in many other fields such as nuclear gas turbines, high speed trains, helicopters, etc.
Inertial navigation so that in the event of spoofing or denial of service of GPS or Galileo, the craft can still navigate. Navigation inertielle pour qu'en cas d'usurpation ou de déni de service du GPS ou de Galileo, l'engin puisse toujours naviguer.
Northrop Grumman makes INS for the US navy although their systems like AN/WSN-7 are classical gyroscope models so the ones shown here are likely substantially better.
Le soleil est bas, les feuilles sont au sol ... Pas besoin d'un système de localisation pour dire que la Terre n'était pas à sa position de juin quand ça été filmé. Je sais, c'est du mauvais esprit de ma part.

wait until quantum navigation comes out.
INS lookin like spaceship stuff
Great video thank you
Cool!
Do not toss your paper charts, sextant and winding clock.
How well will it hold up to a big EMP?
Pretty well. Space craft are usually exposed to a lot of radiation and military vessels already have a lot of protection against EMPs anyway.
Mais le but c'est quoi ? Naviguer sans GPS ?

FO INS. Better than laser
I have no idea who in the US makes similar nav aids. GPS will try to be defeated by the opponent.
