Typical Applications and Advantages of the G-F3G70 Tri-axis Fiber Optic Gyroscope in Guidance and Attitude Control Systems

Core Application: Guidance and Attitude Control

The G-F3G70 tri-axial fiber optic gyroscope (FOG) is specifically designed for medium-to-high precision navigation, guidance, and attitude control systems. It serves as a critical sensing core enabling precision strikes and flight control for tactical weapons such as small missiles and guided bombs. By integrating angular rate sensing capabilities across three axes, it accurately detects the carrier's 3D attitude changes and angular motion in real-time. It provides vital data to the flight control computer, ensuring the weapon platform maintains stable flight along its intended trajectory and strikes the target with precision.

Technical Advantages: High Precision and High Reliability

As an all-solid-state gyroscope, the G-F3G70 inherits the inherent advantages of fiber optic gyroscopes: rapid startup, wide dynamic range, and high reliability. Its superior performance fully meets the requirements of navigation and guidance-grade applications:

· Excellent Bias Stability: The G-F3G70-C model achieves bias stability of ≤0.02°/h (10s smoothing), ensuring an accurate and stable attitude reference during long-duration flight missions.

· High Dynamics and Sensitive Response: The product features a dynamic measurement range of ±300°/s and a bandwidth of ≥200Hz, enabling precise tracking of attitude changes during high-speed, high-maneuverability flight. Additionally, a threshold and resolution of ≤0.01°/h ensure the system's keen sensitivity to minute angular movements.

· Harsh Environment Adaptability: It supports an operating temperature range of -45°C to +65°C and features a lightweight design (under 800g). Combined with the FOG's inherent shock and vibration resistance, it is ideally suited for demanding environments such as missile-borne applications.

Ease of System Integration

The G-F3G70 utilizes an integrated optical-electronic packaging design with a split-unit structure, resulting in a compact form factor and easy installation. The electronics module measures 60×60×24mm, while the sensor head measures Φ67mm×17.5mm. It includes clearly defined M3×4 and Φ2.7×8 mounting holes, facilitating integration into space-constrained weapon systems. The product operates on a standard +5V power supply with a steady-state power consumption of ≤5.5W, and outputs digitized angular rate and temperature data via a high-speed serial port (921600 bps, even parity), greatly simplifying the user's electrical and communication interface design.
