kulmanopeusmittausjärjestelmien
Kulmanopeusmittari (angular velocity meter) is an instrument that measures the rate of rotation around one or more axes. It is commonly referred to as a gyroscope or angular-rate sensor. The data produced is typically given in radians per second (rad/s) or degrees per second (°/s) and is used to determine orientation and motion.
Principle: Traditional mechanical gyroscopes rely on a spinning rotor whose angular momentum resists changes in orientation.
Types: Mechanical gyroscopes are largely historical; MEMS gyroscopes are small and inexpensive and common in smartphones
Applications: Kulmanopeusmittare form the angular-rate input to inertial measurement units (IMUs) used in aircraft, ships, missiles,
Performance and limitations: Measurements can drift over time (bias), have scale-factor errors, and be sensitive to
History: The concept dates to the 19th century with spinning rotors used to demonstrate angular momentum. Developments
