The PAMELA project is the satellite experiment for measurements of the cosmic ray energy spectra in a wide energy range in near-Earth space. The PAMELA apparatus is in orbit from 2006 till today. The calorimeter is the main part of the instrument. It is able to measure energy, to distinguish between hadrons and electrons and to reconstruct the arriving particle direction. Using of special triggers for the calorimeter allows significant increasing of statistics. In consideration of these facts the technique of anisotropy searching in the energy range extending higher than 10 GeV has been developed. This technique is based on the calorimeter data and has as content the advanced method of the reconstruction of the secondary particle shower axis in the calorimeter.
