High-Precision Integrated Navigation System By Fiber Gyro And MEMS Acceleroemter
INS-100 is a high-precision integrated navigation system independently developed by AVIC group. 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.
