JDB-KT-IMU100 micro-inertial measurement unit consists of home-made MEMS gyro chip and quartz flexure accelerometer with independent intellectual property rights, as well as its driving pickup circuit, temperature sensor, digital signal processing circuit and control software. It has built-in algorithms for full temperature compensation, nonlinear compensation, installation error compensation, etc. The angular velocity and linear acceleration of the three axes of the measurement carrier are output through the high-speed RS422 serial port.
The product is characterized by high precision, good repeatability, small volume, shock resistance, low delay, etc. It can be widely used in the fields of photoelectric pod, unmanned platform and attitude control. This series of products can replace foreign products with the same performance, and can provide customized services according to user needs.
