repeatability is getting the same result from doing the same thing - say you use your IMU to fly a plane from dallas to tokyo
do this several times. the repeatability is a measure of your landing in the same spot each time
stability is sitting still and getting the same thing - say you park your plane in denver, and leave the IMU running. stability is it saying your still in the same place
I’m not sure if the „scale factor in-run stability“ is related to the case when the IMU stands still. Attached is an example of both parameters. It seems scale factor in-run stability is measured with the roll = 180 degrees.
