Schuler loop
What it is;
"Schuler loop i only common to a stable-platform INS that has been programmed to remain horizontal as the aircraft moves around the surface of the earth. The error exists at the first accelerometer level, i.e., acceleration, which can be passed up through the integration to affect velocity and distance, resulting in a distance error during the schuler loop cycle, but the error returns to zero at the end of the cycle."
Can anyone come up with a simpler explanation of schuler loop, i've tried trusty google but still finding schuler loop hard to understand
Thanks
