Abstract

The increased precision demands of artillery shells require adapted guidance techniques improving the overall impact probability. To this end, the impact point must be estimated by an Impact Point Prediction (IPP) method in order to correct the ballistic trajectory to hit the target. This paper presents a novel IPP method for the Zero-Effort-Miss (ZEM) guidance techniques based on a Modified Point Mass (MPM) model. The development is focused on improving the IPP accuracy by identifying the roots of uncertainty of existing methods. Nominal trajectory simulation results show a large improvement in the IPP fidelity leading to lower guidance accelerations and actuator demands. This results are confirmed by Monte-Carlo trajectory simulations with uncertainties in launch condition, aerodynamics and environment.
