The Dubhe-M4 Laser Inertial Navigation System (INS-M Series) utilizes a laser gyroscope and quartz accelerometer as its core inertial sensors. Based on a mature strapdown inertial architecture, the system runs high-speed navigation algorithms internally to compute and output navigation information in real time. It supports multiple operating modes including inertial autonomous navigation and inertial/GNSS combined navigation, enabling reliable heading, attitude, speed, and positioning output for maritime platforms.
Designed for high-precision marine integrated navigation system applications, the Dubhe-4 meets the requirements of vessels and unmanned platforms that require stable and good-quality guidance performance. As an experienced INS guidance system provider and manufacturer, the Dubhe product family supports long-term deployment in complex marine environments.
