JDB-KT-EX3-2 series of high-precision three-axis MEMS gyro products are composed of localized MEMS gyro chip with independent intellectual property rights, its driving pickup circuit, temperature sensor, digital signal processing circuit and control software, etc., with built-in algorithms of full-temperature compensation and mounting error compensation, and output high-precision measurement data through high-speed RS422 serial port. This series of products are divided into industrial grade and wide temperature grade (operating 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 series of products with the same performance, and can provide customized services according to user needs.
