High End Gnss Inertial Navigation System for Marine Positioning and Navigation
Product Description
INS-100 is a high-precision integrated navigation system. It is equipped with three self-developed 40 fiber optic gyroscopes, three-self MEMS accelerometers and GNSS modules, and realizes high-precision positioning and navigation in complex environments through multi-sensor fusion and integrated navigation algorithm. The product has high reliability and strong environmental adaptability. The products can be widely used in intelligent driving, UAV, surveying and mapping, marine compass, stable platform, photoelectric pod, underwater vehicle and other fields.
Main functions of the integrated navigation system are as follows:
