SINS-006 fiber-optic strapdown inertial navigation achieves all signal processing in the computer.
Description:
Fiber-optic strapdown inertial navigation is composed of three-axis fiber optic gyroscope and high precision quartz flexible accelerometer, optical fiber I / F conversion circuit, DSP digital signal processor and DC power supply, etc., and adopts digital temperature measurement, flexible PCB traces and Kalman filter technology, to achieve a high inertial measurement accuracy, real-time settlement of large amounts of data, all signal processing in the computer to achieve.
Advantages:
1. Small size, light weight, shock resistance, vibration resistance
2. No traditional mechanical platform, shorten the start-up time
3. Eliminating errors associated with platform-based systems
4. All-round attitude work
Water weapons, small underwater vehicles and guided in the inertial guide
