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.
