Optical Fiber Rotating Inertial Navigation System For UAV Flight Control And Navigation And Positioning
KsINS-G107A fiber optic rotating inertial navigation system
product description:
KsINS-G107A is a single-axis rotating inertial navigation system that uses high-precision fiber optic gyroscopes and quartz flexible accelerometers to suppress navigation error divergence through rotational modulation. It is equipped with a set of satellite receivers by default and has differential positioning and dual-antenna measurement capabilities. It has directional and multi-channel integrated navigation capabilities; the system uses information fusion algorithms to judge the validity of satellite navigation information, timely distinguish deception signals, and support aircraft to safely escape from deception areas. It has astronomical navigation and visual navigation software and hardware interfaces to meet UAV attitude control and navigation and positioning requirements.
Features:
● High reliability, light weight, long endurance and high precision navigation
● Rich and flexible combined navigation modes, smooth switching between modes, and fault-tolerant navigation capabilities
● Adapt to a variety of starting conditions, and can quickly respond to power outages and restarts
● Good vibration-shock-heat composite environmental adaptability
● Have complete BIT design
Application fields and application modes:
It can be applied to all types of large and medium-sized long-endurance UAVs.
