The analysis of algorithms of evaluation of parameters of trajectories of flying objects is conducted at a priori vagueness of indignations in the dynamics of their motion. On the basis of theory of invariance and statement method evaluation algorithms are developed with enhanceable tochnosnimi descriptions. Possibility of diminishing of dynamic errors appears due to the use of additional compensative connections in ductings of filtration and extrapolation. The results of researches are resulted by an analytical method.
