INT-D-M12 Autonomous FOG Ships Inertial Navigation System 24V With Quartz Accelerometers

Product Description

Maritime RLG INS(INT-D-M12)


Our advanced marine inertial navigation system combines laser/FOG technology with quartz accelerometers in an innovative "strapdown with modulation" configuration. The high-speed navigation computer processes real-time data to deliver superior accuracy across multiple operational modes - including autonomous inertial, satellite-aided, and velocity-combined navigation - ensuring comprehensive positioning solutions for all marine applications.
