Model U33 High Accury There-axis Fiber Optic Gyroscope With 0.5 °/hr Bias Drift

Model U33 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 U33 fog is an inertial sensor developed for tactical military systems. U33 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.

1.2 Overall dimensions

Overall dimensions:90mm×90mm×90mm,

The pitch of the installation:(71.5±0.05)mm×(71.5±0.05)mm,Install screw M5

1.3 Weight

1050g±50g
