TYF72A-A4L Airborne Fiber-Optic INS High-Precision Strapdown and INS-GNSS Integrated Navigation System

The device is designed for applications requiring reliable attitude, heading, and position information under demanding dynamic and environmental conditions.
The system is available in two configurations:

General INS (without GNSS)

Integrated INS/GNSS (built-in GNSS receiver)

This product is suitable for UAVs, UGVs, guided weapons, marine platforms, surveying equipment, and other inertial navigation applications.
