JDB-KT-EX6-1 series high-precision micro-inertial measurement unit consists of localized MEMS gyro chip and MEMS accelerometer chip with independent intellectual property rights, as well as its driving pickup circuit, temperature sensor, digital signal processing circuit and control software, etc. It has built-in algorithms of full-temperature compensation, non-linear compensation and installation error compensation, and outputs the three axial directions of the measurement carrier through the high-speed RS422 serial port, including angular velocity and linear acceleration. Through the high-speed RS422 serial port output to measure the carrier three axial angular velocity and linear acceleration. This series of products are divided into industrial grade and wide temperature grade (working temperature -55℃~+85℃).
The products are characterized by high precision, good repeatability, small size, shock resistance, low delay, etc. They can be widely used in the fields of optoelectronic pods, unmanned platforms, attitude control, and so on. This series of products can replace the foreign equivalent performance series products, and can provide customized services according to user needs.
