Product Overview
This system adopts high-precision closed-loop fiber-optic gyroscopes (FOG) and accelerometers, combined with professional-grade GNSS boards. It provides accurate dynamic information such as 3D acceleration and angular velocity, serving as a high-performance inertial measurement unit (IMU).
It can achieve initial state north-seeking without the need for auxiliary heading aids such as dual-antenna receivers.
