M5000 is a compact, lightweight, Pressure-Proof Fiber-Optic Strapdown Inertial Navigation System. It includes a three-axis high-precision fiber-optic gyroscope, high-precision quartz-flex accelerometer, a mobile mapping-grade multi-frequency GNSS receiver with standalone positioning capability, and an optional Doppler Velocity Log (DVL). 

The satellite-aided M4000 (abbreviated as "M4000") is a fiber-optic strapdown inertial measurement unit. This M4000 can operate in two modes: integrated navigation (GPS integration, log integration) and undamped mode, outputting information such as attitude, position, velocity, and heave. ⚪  Scope of application: Marine surveying and mapping; Surface and underwater warships; ⚪  External sensors compatible with the product: GPS (single-ended or differential), with options for built-in GPS board or external GPS information input; DVL Doppler sensor.

M2300 MEMS inertial navigation device can be used to measure motion parameters such as three-dimensional attitude, angular velocity, and acceleration of moving carriers.The device mainly consists of three orthogonal single axis high-performance MEMS gyroscopes, one three-axis MEMS accelerometer, and related power conversion, acquisition, and calculation circuit boards. The M2300 product adopts high-performance microprocessors and advanced dynamic calculation and EKF algorithms, which can effectively remove the interference of accelerometers under dynamic conditions and the accumulated drift error of gyroscopes. It can provide real-time key information required for ship maneuvering and other surface and underwater vehicles, such as the three-dimensional attitude angle (geographic heading angle, pitch angle, and roll angle), carrier angular velocity (azimuth angular velocity, longitudinal angular velocity, and lateral angular velocity), instantaneous displacement (heave, pitch and roll), and short-term high-resolution positioning data.

Fiber optic gyroscope compass is a new generation of strapdown compass system for civilian ships. It uses advanced fiber optic gyroscope and strapdown calculation technology to autonomously measure the ship's angular motion, and has the ability to continuously provide the carrier's heading, pitch, roll and other information to the outside world, providing basic information support for ship navigation at sea. Fiber optic gyro compasses have the advantages of long lifespan, maintenance free, short start-up time, low cost, and no need for regular replacement of gyro balls, which can completely replace traditional gyro compasses.
