Unified systematic of elastic scattering data (USESD) proposed by the authors(arxiv:1111.4984 [hep-ph]) is based on symmetrized 2-dimensional Fermidistribution for pp elastic scattering amplitude in the impact parameterrepresentation. It allows to describe differential cross sections of thereactions up to |t| ~ 1.75 (GeV/c)$^2$. To extend it to higher |t| values weconsider a two coherent exponential parametrization of the cross sections andshow that it cannot describe the cross sections at small |t| at $P_{lab}>$ 10GeV/c. We extract a description of high |t| region from the parameterizationand couple it with USESD. As a result, we obtained a good description of all ppelastic scattering data at $P_{lab}>$ 10 GeV/c. It can be easily used inGlauber Monte Carlo codes for calculations of nucleus-nucleus interactionproperties.
