To the ADCS engineer, it is all noise, but understanding its source characteristics may be instrumental in removing or coping with it. WebJan 1, 2013 · If the attitude were defined with LOS direction of certain attitude reference sensor, the difference might be much larger, since the LOS direction is thought to be roughly equal to the rotation of the sensor base plate that is also subject to vibration. And the attitude thus defined may be out of phase with pointing jitter.
