Gyroscope

Physically the Gyroscope measures the rotational velocity on three axis. By 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 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.
