Product Description

The Dubhe-M1 Submarine Inertial Navigation System (INS) is designed to meet the demands of maritime and submarine navigation. Integrating precision RLG/FOG gyroscopes with quartz accelerometers in a robust strapdown sensor assembly, the system provides high-accuracy, real-time navigation data.

Equipped with a high-speed processing unit, the Dubhe-M1 supports multiple operation modes, including pure inertial navigation and GNSS/velocity hybrid navigation, ensuring continuous and reliable positioning information for a variety of marine platforms.

Applications:

Submarines and underwater vessels
Maritime vessels requiring precise navigation

Key Features and Capabilities:

Real-time strapdown computation for accurate navigation
Pure inertial and GNSS/velocity hybrid operation modes
Reliable continuous positioning for diverse marine platforms
High-precision heading, roll, pitch, speed, and position information

Keywords: Submarine INS, RS422 strapdown INS, maritime RLG INS, GNSS-aided marine navigation, optical strapdown INS, high-accuracy marine INS, FOG gyroscope navigation
