These devices have almost no moving parts, can weigh less than two pounds and can measure aircraft movement on a three dimensional surface to less than 2 nm after one hour
They only use the speed of light to calculate how far the aircraft has moved in three dimensions

Interesting device, did not know it exists.
It seems strange to me that they can measure the difference between speed of light of 2 lasers.
Doesn't this brake Einstein's special theory of relativity? The speed of light should be the same, no matter if one light is accelerated and the other one decelerated (through rotation clockwise and anticlockwise).
And if these inertial navigation systems exist and are this accurate, why can't one be used to show the movement ad acceleration of Earth through space? The only proof for that is the Foucault pendulum.

1. speed of light is constant. If the device moves then there will be a difference in time for light to travel across the device and so the amount of movement is known
2. These devices are able to calculate the current position relative to a known point with an accuracy of less than 2nm after one hour. That error would compound after many hours.
3. Why are you saying that the pendulum is the only proof of the movement and acceleration of the earth thru space?
I'm sorry you are having issues here. You owe it to yourself to question your indoctrination process. If you really care for yourself.
If you want to talk about your theories about my psychological state please begin a thread for that purpose.
This thread is about the ability of pilots to realise if they are descending in three dimensional space as they fly at a constant altitude above the surface.

Well, if speee of light is constant, but only travels a different distance due to the movement of the gyroscope, then why did the Michaelson-Morley experiment failed?
An interferometer placed anywhere on Earth will have the same phenomenon happening as the gyroscope.
As the Earth moves, the light on one arm of the interferometer will take longer to reach its destination then the light on the other arm.
As the Foucault pendulum, I don't know of any other EXPERIMENT to show that the Earth is moving.

michaelson morley was looking for the medium that light is propagated by to be moving. Ie the Aether wind.
I have no idea why the device does not detect the movement of the earth. The ring laser gyro uses the Sagnac effect which might be a clue to the answer
EDit.
OK i now understand more about michaelson morley and more about how the gyro works. So speed of light cannot be used to measure speed of earth? What was the doppler shift measured by hubble? But it does not matter.
A ring laser gyro measures the different distance light has to travel when two beams of light travel in different directions thru the device when the device is rotated.
I was told years ago around 1990 by an airline pilot that light was used to navigate using 3 beams - as i recall it - and something like that seems to be true. You just need a few gyros

This is what I am saying.
Einstein showed us that a body is only in motion in relation to another.
According to his theory, if we were on a train which moved at a constant speed in perfect conditions, whithout accelerating or decelerating and whithout friction, it would then be impossible for us to say that we were moving, if we didn't have another body to take as a reference.
Yet this gyroscope device can register and calculate motion without referencing to an external body.
So absolute motion can then be detected and calculated.
So then why can't we use this or a similar device to record and calculate Eart's motion through space??
matt, I think Nasa claims they have a video with a timelapse of Earth rotating. Some people say it's fake because clouds are not moving, and other claim clouds are moving. I am going to check it out.

Yes, I have seen two such claims, one even with the moon going past the camera.

The ring laser gyro is accurate to a rotation of 0.01 degree per hour.
So in an inertial guidance system a 747 travelling west parallel to the surface of a round earth at 900kmh per hour will have rotated 8.1 degrees and have a known position along that latitude compared to an accurate lat and long of +/- 0.6nm longitudinally. Whatever direction the 747 flies for the same height on a round earth it will haverotated to give a new latitude and longitude on a round earth and no detectable rotational change on a flat earth
