built up the rigid body trajectory model of TV-guided shell, and analyzed the effect of angle-of-attack on guidance precision of TV-guided shell. Simulated trajectory of inertial guidance glide phase in an initial condition based on MATLAB. Get angle-of-attack and the error caused by angle-of-attack.Advance a way of correcting balance angle-of-attack to eliminate error, which provides a theoretical foundation for improving TV-guided Shell guidance precision.
