On basis of the analysis of technical decisions aimed at improving the hit accuracy of unguided rocket projectiles (UR) for multiple launch rocket systems (MLRS) proposed the concept of creating high-precision UR with guided warheads (GW), separated from a rocket part. Proposed three-step guidance on GW goal. The structure of dispersion of points falling GW concerning the aimpoint is presented, the estimation of scales of the factors causing technical dispersion is carry out, the formula for an estimation of its demanded value is offered. The estimation error of calculating the coordinates of GW for solving navigation tasks on information from various types of navigation system without platform.
