To solve the problem of attitude measurement for high spin rate projectiles,the magnetometer/yawsonde integrated attitude determination method is studied.The measurement equations of triaxis magnetometer and yawsonde are established.A novel attitude algorithms for triaxis magnetometer is provided and the existence of solutions is investigated.The magnetometer/yawsonde nonlinear measurement equations are solved using an analytical algorithm so as to avoid the convergence of a numerical method.Simulation results show that magnetometer/yawsonde integrated attitude determination can achieve high accuracy.The research results provide an effective method for attitude measurement of high spin rate projectiles.
