In work variants of realisation of discrete algorithm of support of the maneuvering purpose, received on the basis of an incorporated combined maximum principle (CMP). Results of mathematical modelling of the filter of support CMP on the basis of Euler's method (23) and Euler's method with recalculation (24), (25), averaged on 100 runs, show that in comparison with α?β the filter [7] filter CMP (23) at a maneuver stage provides reduction of errors of estimation on the average on 30% and 60% accordingly. The filter of support CMP (24), (25) at a maneuver stage provides on the average level of errors of estimation corresponding to level of errors of filter Kalmana. However the offered filter functions at essentially smaller computing expenses. On a site of rectilinear and uniform movement of an estimation of errors of the offered filters of support on the average coincide with estimations α?β the filter and filter Kalmana.
