Physicall Physically the Gyroscope measures the rotational velocity on three axis. By integra-tion integration the orientation change since the last update can be calculated. Consequently the Gyroscope can´t provide absolute orientation, but is able to propagate the orientation once it is initialized.
== Characteristics ==
* Provides orientation in world coordinates once it is initialized by another orientation estimation system (e.g. [[AR-Marker]] or [[Compass]])
* The orientation can be propagated accurately, characterized by a growing er-ror error of roughly 0.05° per second.
* Very low standard deviation.
* The orientation is updated with roughly 250Hz.
* Very fast and responsive.
* Requires a Gyroscope sensor.
