In June of this year some members proposed that we use a fiber optic gyro (FOG) or an inertial measurement unit (IMU) to test if while flying in an airplane tilts in reference to space as it flies over the convex surface of the earth. This is what is expected under a globe earth model. But as tests were conducted it was concluded that we could not prove that the IMU or FOG was not in fact being influenced by gravity in testing its orientation. If we can’t verify that it is giving a result totally independent of gravity then no test with them can produce useful data. So it was decided to pursue using mechanical gyroscopes to provide the rigidity in space reference.
Rick Zimmerman is an FECORE member living in the US. He has been experimenting with IMUs and mechanical gyros. Rick tests to see if the gyro will remain fixed in space over a long period of time. He found that they do not. By placing the gyro on a platform which can be set to rotate at a specific rate for example 15° per hour and the gyro is free to turn independent of the table then after one hour the position of the gyro should be 15° different.
But what Rick has found is that none of the commercially available gyros can be trusted to remain fixed in space for hours at a time. They all have some precession. They slowly move on their own relative to the known movement of the table. One brand will move more than the rotation at times and less than the movement at other times. In no case do any of them move in accordance with the theory of the spinning earth. But that is not proof of anything since they move on their own no matter what the table is set to or even if it is not turning. Well it is proof of one thing. So far no commercially produced gyro remains stable in space. They all move on their own.
So we have determined to build a better gyro. A gyro that has the ability to remain fixed in space within the tolerance to test actual turns and not rely on accelerations which are all relative movements. We will keep you updated.
