文摘
- •
The gyroscope structure electronic model and the noise components are analyzed.
- •
A interface is proposed based on weak signal differential detection technology.
- •
A quadrature error compensation system is used to observe Coriolis signal noise.
- •
Flicker noise is the dominate one in structure and is suppressed by the interface.
