JDB-KT-EX2-1 high-precision dual-axis MEMS gyro consists of a localized MEMS gyro chip with independent intellectual property rights and its drive pickup circuit, temperature sensor, digital signal processing circuit and control software, etc. It is used to measure the two horizontal axial angular rates of the carrier in real time, and outputs the two angular rate information after error compensation through the RS-422 serial port. Error compensation includes temperature compensation, mounting angle compensation, non-linear compensation, etc.
The product has the characteristics of high precision, small volume, light weight, anti-shock, anti-electromagnetic interference, etc. It can still work reliably in harsh environments, and can be widely used in the fields of optoelectronic pods, unmanned platforms, attitude control, etc. The product can replace the dual-axis angular rate in situ. The product can replace the dual-axis power tuning gyro in-situ, and can provide customized services according to user needs.
