Paper Abstract

In this paper, a filtering algorithm is studied for the agile projectile's attitude determination. An incomplete inertial measurement unit (IMU) composed of only three low-cost micro electro-mechanical system (MEMS) accelerometers is used to determinate the attitude of agile projectile. Considering the gravity vector remains constant around the firing position in a short time, the agile projectile's attitude and rotary speed in flight is estimated by using filtering algorithm according to the information of three accelerometers. The experimental results in three-axis flight rotary table show that the filtering algorithm in this paper quickly converges and the precision of estimation is high.
