KsINS-90 type optical fiber strapdown inertial navigation system
product description:
The KsINS-90 fiber optic gyroscope strapdown navigation system is based on a universal fiber optic inertial navigation platform. The platform adopts a universal design concept and is easy to make adaptive changes according to user needs. It has the advantages of short development cycle, high maturity, and good reliability. ; Its supporting gyroscopes, accelerometers, circuits and other components are all made from our existing shelf products, which are mature and reliable.
Features:
● Using domestic fiber optic gyroscope and quartz flexible accelerometer
● The bias stability of type 90 fiber optic gyroscope is better than 0.01°/h (1σ)
● Accelerometer bias stability is better than 50µg (1σ)
● Compatible with static and dynamic base alignment methods, self-alignment and transfer alignment can be selected according to user needs
● Can integrate navigation with external information such as satellite navigation instrument, speedometer, odometer, altimeter, etc., with strong scalability
Application fields and application modes:
Land use, navigation, drones, and can also be extended to other applications.
