Description
The OC-300DL-DGI Fiber Optic Integrated Navigation System is built upon cost-effective closed-loop fiber optic gyroscopes (FOG), accelerometers, and high-end GNSS receiver boards. Through multi-sensor fusion and navigation algorithms, it meets the precise measurement requirements for attitude, heading, and position in applications such as medium-to-high precision mobile mapping systems and large UAVs. The product features integrated inertial/satellite navigation and pure inertial modes. In integrated mode, it outputs data compatible with NovAtel’s IE post-processing software. Upon activation, the pure inertial mode (defined as no GPS fusion since power-on; signal loss after fusion is classified as integrated mode) provides precise attitude measurement, outputting pitch, roll, and heading, and supports static north-seeking.
