MEMS Sensor-Based Attitude Measurement of Projectile Body

Given the application requirements of miniaturized measurement of the attitude of the projectile, the method of applying MEMS sensors to acquire the overload, rotational and geomagnetic parameters of the projectile, and then solving to obtain the attitude parameters, is investigated. A telemetry acquisition coding circuit is designed and implemented to acquire MEMS sensor data with an FPGA device. A model for solving the attitude of the projectile has been constructed, and the solving of the attitude parameters of the simulated projectile under laboratory conditions has been preliminarily achieved, which can provide technical references for the subsequent accompanying tests of various types of miniaturized maneuver targets.
