Description
The OC-300AL-DGI Fiber Optic Integrated Navigation System integrates cost-effective closed-loop fiber optic gyroscopes (FOG), accelerometers, and high-end GNSS receiver boards. Utilizing multi-sensor fusion and navigation solution algorithms, it meets the precise measurement requirements for attitude, heading, and positioning in applications such as medium-to-high precision mobile mapping systems and large-scale UAVs. The product features Integrated INS/GNSS and Pure Inertial navigation modes. In Integrated mode, it utilizes GNSS satellite positioning data to output pitch, roll, heading, position, velocity, and timing. Upon signal loss, it outputs inertial-derived position, velocity, and attitude data, maintaining high precision for pitch and roll, while providing short-term heading retention and meter-level positioning accuracy. In Integrated mode, it supports raw data output for NovAtel’s IE post-processing software. Pure Inertial mode (referring to operation without GNSS fusion since power-on; signal loss after fusion remains in Integrated mode) provides precise attitude measurements, outputting pitch, roll, and heading, and supports static north-seeking.
