The instrument consists of magnetic spectrometer, imaging electromagnetic calorimeter, time of fight system, anticoincidence and neutron detectors that provide unique particle identification and background rejection in wide energy range from 50 MeV up to hundreds GeVs. PAMELA was collecting data since June 2006 till January 2016. The satellite orbit with 350-600km initial altitude and 700 inclination crosses the inner radiation belt in South Atlantic Anomaly at L-shell 1.2. The trajectories of trapped electrons and positrons in the Earth magnetic field were reconstructed by means of a trajectory tracing simulation. In this work PAMELA's spectral measurements are compared with those of other spacecraft and with theoretical predictions.
