Model U32 High Accury There-axis Fiber Optic Gyroscope With 0.5
°/hr Bias Drift
1. Product introduction
1.1 Working principle and functions
The strapdown inertial group of U32 fog is an inertial sensor
developed for tactical military systems. U32 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.
