Anti-Interference Integrated Fiber Optic Gyro / Mechanical Gyroscope
Product Description
Featured with independent of outside information, excellent
concealment, strong anti-interference, all weather operations,
Attitude and Azimuth Integrated Navigation Vertical Fiber Optic
Gyros is a complete autonomic navigation system which could provide
diverse navigation parameters. However, its output error is
accumulated along with time. Global position satellite (GPS) has
higher navigation accuracy, but it is easy to be interfered,
suffered from discontinuous output and incomplete output
information etc. In order to integrate the advantages of these two
navigation methods and effectively improve product performance, as
well as strength product's reliability, availability, environment
adaptability and dynamics, we utilizing multi-sensor data fusion
technology to combine satellite positioning, orientation and
inertial measurement, and release new attitude and position
integration navigation system.
