The RL90 Ring Laser Gyro Inertial Navigation Device is a high-performance inertial measurement product. It utilizes the Model 90 Ring Laser Gyro and flexible quartz accelerometer, ensuring accurate and reliable navigation data. With meticulous error calibration and compensation, the system delivers exceptional precision. Its design features, such as electromagnetic shielding, thermo-balance, vibration mode, and sealing, guarantee excellent environmental suitability. The RL90 achieves a CEP of 1.0 nmile (4h) in pure inertial navigation mode and provides integrated navigation accuracy of less than 5 meters (1σ) when combined with GNSS. It offers outstanding heading angle accuracy of 0.01° RMS and horizontal attitude (roll and pitch) accuracy of 0.005° RMS. The system also provides reliable velocity data, with pure inertial velocity accuracy at 1.0 m/s RMS and GNSS integrated navigation velocity accuracy at 0.1 m/s RMS. The RL90 is the ideal solution for applications that require precise and dependable navigation performance.
