The TYF72A-A4L is a high-precision airborne fiber-optic inertial navigation system (INS) designed for applications requiring reliable attitude, heading, and position information under demanding dynamic and environmental conditions. It is available in two configurations:

• General INS (without GNSS)

• Integrated INS/GNSS (with built-in GNSS receiver)

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