The KT-EX7-2 attitude measurement unit consists of a domestic three-axis gyroscope, a domestic three-axis accelerometer, a temperature sensor, a signal processing board, a structure and necessary software. It is used to measure the three-axis angular rate, three-axis acceleration and horizontal attitude angle (including pitch angle and roll angle) of the moving carrier. The attitude is output through algorithms such as the 9th-order Kalman filter and in accordance with the agreed communication protocol. Attitude angle information and inertial navigation information.
