The development of the software package method created by Yu.S. Osipov and A.V. Kryazhimskii for the problem of guaranteed  positioning guidance on a closed convex target set is considered at a given time for a linear controled system. The observed signal of the  system state is linear; its set of acceptable initial states is assumed to be finite. An algorithm for constructing the guidance package and the corresponding guidance positioning strategy is described structurally using the stated equivalence of the guaranteed positioning, package, and expanded program guidance problems.
