Model DINS-200 High Precision Single-Axis Rotating Laser Gyroscope Inertial Navigation System
Introduction
DINS-200single-axis rotating laser gyroscope inertial navigation system is a high-performance inertial navigation and measurement equipment.DINS-200 adopts high-precision laser gyroscope and quartz flexible accelerometer, and the system performance is significantly improved through high-precision error calibration, temperature compensation technology and single-axis rotating online self-calibration and error self-compensation technology. Electromagnetic shielding design, thermal balance design, vibration mode design, sealing design and strict manufacturing technology are adopted in the system to ensure excellent environmental adaptability.
Features
♦ High-precision two-frequency mechanically dithered laser gyroscope.
♦ On-line self-calibration and error self-compensation of single-axis rotation.
♦ Anti-disturbance traveling self-alignment.
♦ The input interface is rich, which supports the reference information access satellite navigation system/odometer/Doppler log/electromagnetic log/altimeter/ultra-short baseline underwater acoustic positioning system.
♦ There are various working modes, and the pure inertia/damping/integrated navigation mode can be selected automatically or manually according to the external reference information.
♦ Excellent environmental adaptability.
♦ Military standard.
