Abstract :
Employing a coil assembly to drive a magnetic rotor makes a two-axis gyroscope simple and compact. A conventional coordinate-transformation method is introduced to derive the dynamic equations related to the gyroscope and to analyze the sensor coils that can provide the information about the gyro position with respect to the vehicle axis. By small angle approximation, a new simplified linear model for analyzing the two axis gimbaled platform of the navigation system is proposed. Within λ≤20°, it is successful to explain the performance of the platform.
