Tactical missile guidance system

Customer Background

A defense research institute developing guidance and control systems for tactical missiles required high-precision, high-reliability, rapid-start inertial sensors.

Challenges

• Missiles experience high-G and high-angular-rate maneuvering, demanding high dynamic response.
• Guidance accuracy requires bias stability better than 0.1°/h.
• No preheat time available pre-launch; must achieve nominal accuracy within 3 seconds.

GyroSens Solution

• GyroSens provided the GSGYR312F-H high-precision three-axis FOG:
• Bias stability <0.1°/h (10s smoothing), bias repeatability <0.1°/h, random walk <0.01°/√h.
• Bias magnetic sensitivity <0.05°/h/Gs, effectively suppressing external magnetic interference.
• Dynamic range ±500°/s, bandwidth ≥200Hz for high-maneuverability flight.
• 3-second rapid startup, reaches nominal accuracy immediately with no preheating.
• All-solid-state design with excellent shock and vibration resistance.
• Operating temperature -45°C～+70°C, storage -55°C～+80°C.

Results

The missile guidance system demonstrated stable performance across multiple flight tests, with CEP meeting design specifications. This gyroscope is now included in the missile's standard equipment catalog.
