Fiber Optic Gyroscope Inertial Navigation System with ≤ 20W Power Consumption, 0.01°/h Bias Stability, and -40℃ to +65℃ Operating Temperature
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.
