What is gyroscope12/25/2022 Since then, Hydrodynamic Gyroscope or Vibrating Gyroscope were used for mass-produced automobile orĬamera and changed its image of expensiveness or short operating device. Therefore, a lot of Japanese manufacturers were interested in and focused on these The accuracy of these Gyroscopes is not very high, but they are superior in operating life, environmental In 1970’s, Hydrodynamic Gyroscope such as Gas Rate Gyro and Vibrating Gyroscope was actively developed in US. Gyroscope was in practical use in 1980’s, and Fiber Optic Gyroscope followed in 1990’s. In thoseĭays, Strapdown Gyroscope was gradually increased while Platform Gyroscope was decreasing.įrom 1980’s to 2000, mechanical Gyroscope was replaced by non-mechanical Gyroscope. In 1980’s, Inertial Navigation System by Strapdown Ring Laser Gyro was adopted by Boeing and Airbus. Therefore, high accuracy gyroscope is needed for dead reckoning. Depending on the accuracy of gyroscope, errors of heading is accumulated. In dead reckoning, position data is estimated by integral of gyroscope, odometer and accelerometer. However, the accuracy of localization is worsened in Tunnel or Multipath propagation. Most items that have spinning wheels somewhat resemble a gyroscope. Through the use of GNSS with centimeter-level positioning accuracy, fully autonomous driving will come closer to realization. Gyroscopes have some really cool applica t ions.
