KsINS-II fiber optic strapdown inertial navigation system
product description:
The KsINS-II optical fiber strapdown inertial navigation system is a
miniaturized and general-purpose inertial navigation system using
high-precision fiber optic gyroscopes and quartz flexible
accelerometers. The system can be sensitive to the angular and
linear motion of the UAV carrier, and output the carrier's
position, speed, heading, angular rate, and linear acceleration
information 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
● Using dual-board working mode, 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
● Nationally produced products
Application fields and application modes:
It can be used in the fields of high-altitude airships, rotary-wing
UAVs, and fixed-wing UAVs.
