GSINS025C Miniature FOG Integrated Navigation System

GSINS025C achieves attitude <0.01° and heading <0.05° within an 80×80×84mm enclosure weighing just 0.8kg—one of the smallest FOG-based INS systems at this accuracy level. Power consumption below 12W and RTK-ready design support centimeter-level positioning. DVL, odometer, and USBL fusion capabilities make it ideal for UAVs, UGVs, and underwater vehicles where every gram and millimeter counts.

Feature:
● High-Precision Angular Velocity Measurement
● Strong Anti-Interference Capability
● Compact and Lightweight, Suitable for Space-Constrained Applications
● No Mechanical Wear, Longer Service Life
● Rich Interfaces, Compatible with DVL, Odometer, and USBL

Product Introduction

A fiber optic inertial integrated navigation system integrates an Inertial Navigation System (INS) with other navigation systems such as the Global Navigation Satellite System (GNSS). By using algorithms like Kalman filtering, it fully leverages the advantages of the inertial navigation system—high short-term accuracy and strong autonomy—and the global navigation satellite system—stable long-term accuracy. This integration suppresses the respective errors of each system, achieves optimal calculation of the carrier's position, velocity, and attitude, and enhances the reliability and stability of the navigation system.

The fiber optic inertial integrated navigation system consists of an Inertial Measurement Unit (IMU), a satellite navigation receiver, a navigation computer, and a data transmission interface.

TheGSINS025C Fiber Optic Inertial Integrated Navigation System is a miniaturized fiber optic inertial integrated navigation system with a volume of only 80×80×84mm and a weight of merely 0.8kg. Composed of a 3-axis integrated fiber optic gyroscope, a quartz accelerometer, and a full-system multi-frequency satellite module, this system is widely used in the navigation and attitude measurement of aerospace vehicles, unmanned vehicles, and ships.
