Abstract

This paper contributes to a new type of guidance scheme dedicated for artillery rocket. It is based on trajectory tracking method. It was assumed that rocket is equipped with a finite set of single use solid propellant side thrusters. Frequency modulation method was used to achieve effective firing logic. The proposed guidance scheme is used in two phases of flight, i.e. in the active portion of the trajectory and in the phase just before target hit. Correction engine activation sequence was chosen in such a way that possibility of rocket axial unbalance is minimized due to motor firing. The numerical simulation results indicate that significant dispersion reduction was achieved and number of activated side rocket thrusters is minimized. Better overall performance was achieved when compared to another state of the art methods.
