Product Description

The Dubhe-70 Ring Laser Gyroscope (RLG) is a high-precision, military-grade inertial sensor engineered for modern integrated navigation systems and INS navigation systems requiring reliable performance in harsh and mission-critical environments.

Based on Sagnac interferometry, the Dubhe-70 delivers exceptionally stable angular rate measurement, enabling accurate guidance, attitude determination, and long-term inertial positioning. Its hermetically sealed optical cavity and rugged construction make it ideal for demanding defense and aerospace applications where good-quality guidance and robust INS performance are essential.

As a trusted INS guidance system component, the Dubhe-70 integrates seamlessly into advanced integrated navigation systems, missile guidance INS navigation systems, marine gyrocompass units, and aerospace attitude control platforms. With proven battlefield reliability, it supports high-accuracy targeting, navigation, and stabilization without reliance on GNSS.

Applications

The Dubhe-70 Ring Laser Gyroscope is widely deployed in:

Spacecraft and space platform navigation systems
Avionics and airborne inertial navigation systems
Satellite positioning and attitude control
Naval vessels and surface combat platforms
Submarine navigation and underwater inertial systems

Mission-Critical Advantages

Factory-aligned optical assembly, ensuring long-term stability and reduced calibration effort
SWaP-optimized design (Size, Weight, and Power), ideal for constrained military platforms
Ruggedized, battlefield-proven durability, resistant to shock, vibration, and harsh environments
High-bandwidth digital output, supporting real-time navigation, guidance, and control

The Dubhe-70 Ruggedized RLG offers high precision, strong environmental robustness, and proven operational reliability, making it a trusted core sensor for military-grade INS, submarine navigation systems, and defense applications.
