KsINS-120 fiber optic strapdown inertial navigation system
product description:
The KsINS-120 fiber optic gyro strapdown navigation system is based on our institute's fiber optic inertial navigation universal platform. This platform adopts a universal design concept and is easy to make adaptive changes according to user needs. It has a short development cycle, high maturity and good reliability. and other advantages; its supporting gyroscopes, accelerometers, analog-to-digital conversion circuits, navigation computers and other components are all products on our shelves, which are mature and reliable.
Features:
● Using domestic 120 type fiber optic gyroscope and quartz flexible accelerometer
● The bias stability of the 120 type fiber optic gyroscope is better than 0.005°/h (1σ)
● Accelerometer bias stability is better than 50μg (1σ)
● Achieve static and dynamic base alignment, and can choose self-alignment or on-the-fly alignment according to user needs
● It can be integrated with various information such as satellites, laser speedometers, odometers, altimeters, etc. for combined navigation, and the interface has strong scalability
