JDB-KT-EX9-1 high-precision micro-inertial measurement unit consists of localized MEMS gyro chip with independent intellectual property rights, MEMS accelerometer chip, magnetometer and barometer and their driving pickup circuits, temperature sensors, digital signal processing circuits and control software, etc. It has built-in algorithms of full-temperature compensation, nonlinear compensation, installation error compensation, etc., and outputs three axes of the measurement carriers, angular velocity, linear acceleration, magnetic field strength and atmospheric pressure via a high-speed digital interface. Through the high-speed digital interface output measurement of the carrier's three axial angular velocity, linear acceleration, magnetic field strength and atmospheric pressure.
The product is characterized by high precision, good repeatability, small size, shock resistance, low delay, etc. It can be widely used in the fields of optoelectronic pods, unmanned platforms and attitude control. This series of products can replace the foreign series of products with the same performance, and can provide customized services according to user needs.
