Physicall the Gyroscope measures the rotational velocity on three axis. By integra-tion 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 of 0.05° per second.
- Very low standard deviation.
- The orientation is updated with roughly 250Hz.
- Very fast and responsive.
- Requires a Gyroscope sensor.
