IMU (Dubhe-IMU1)
The Optical Inertial Measurement Unit (IMU) employs gyroscopes and accelerometers in a strapdown configuration, performing real-time data output according to specific protocols after compensating for installation errors and temperature effects. Applications include missile systems, pod-mounted equipment, and platforms requiring precise angular/linear rate measurements.
Key features:
1) High accuracy and stability with flexible design;
2) All-solid-state construction without moving parts;
3) Fast startup with digital output for easy integration;
4) Low noise, power consumption and cost;
5) High reliability and long service life.
