Product Description
High Precision Navigation MEMS IMU for Inertial navigation with built-in 3 Axis Gyro
The KT-EX 9-2 multi-degree-of-freedom inertial measurement unit is a complete inertial system with a built-in three-axis gyroscope, a three-axis accelerometer, a three-axis magnetometer and a pressure sensor for measuring the three-axis angle of the carrier parameters such as rate, acceleration, three-axis magnetic field, air pressure, etc., output data after error compensation (including temperature compensation, installation misalignment angle compensation, nonlinear compensation, etc.) according to the communication protocol through SPI.
