Overview

The F45 underwater fiber optic inertial navigation (INS) is a cost-effective integrated navigation product that can autonomously integrate GNSS, DVL, USBL and other sensor data based on information availability, and independently complete sensor error calibration, ensuring navigation accuracy while greatly simplifying system integration difficulty. The advanced seamless navigation technology adopted by the product fully solves the problem of state fluctuations in the navigation system when switching sensor fusion types between underwater and surface, making the entire navigation process stable and smooth. It is an ideal solution for ship compass, underwater unmanned submersible navigation, and land positioning and orientation standards.
