Model U30 High Accury Single-axis Fiber Optic Gyroscope With 0.5 °/hr Bias Drift
1. Product introduction
1.1 Working principle and functions
The strapdown inertial group of U30 fog is an inertial sensor developed for tactical military systems. U30 by three solid-state fiber optic gyroscope, quartz flexible accelerometer, data packaging board, ontology structure and related software and so on, measure the angular velocity and linear acceleration of the vehicle movement, and temperature, install the misalignment Angle, nonlinear, zero error compensation, as the carrier's attitude and navigation control to provide information, measurement results through RS422 serial bus output.
