Our IG family products uses the gravity vector as the local vertical reference. This gravity is measured by accelerometers, and cannot be differentiated from other sources of acceleration. Linear accelerations can affect performance in attitude estimation. The Kalman filter used in IG-500 devices is designed to be the least dependent on the gravity vector measured by accelerometers, and only long acceleration will affect quality of orientation.
