Fiber Strapdown Inertial Navigation System For High Altitude Airships And Fixed Wing UAVs
KsINS-nano fiber optic strapdown inertial navigation system
product description:
KsINS-nano optical fiber strapdown inertial navigation system is a miniaturized universal inertial navigation system using high precision fiber optic gyro and quartz flexible accelerometer. The product adopts compact design.
The system can be sensitive to the angular and linear motion of the UAV carrier, and output the position, speed, heading, angular rate, and linear acceleration information of the carrier in real time. It can be combined with a satellite receiver to complete integrated navigation operations, which can meet the needs of various UAVs. Attitude control, navigation and positioning requirements.
Features:
● Small size, light weight, high precision, good production technology and high reliability
● Rich communication interfaces
● The output protocol is flexible and can be configured through test software
● Vibration reduction accessories are provided to meet the needs of harsh vibration environments
● Have a complete BIT strategy and passed the actual flight assessment
Application fields and application modes:
It has been maturely used in the fields of high-altitude airships, rotary-wing UAVs, and fixed-wing UAVs.
