CSES-01 (China Seismo-Electromagnetic Satellite) is a mission developed by CNSA (Chinese National Space Administration) and ASI (Italian Space Agency) to investigate the near-Earth electromagnetic, plasma and particle environment, focusing on the disturbances of the ionosphere-magnetosphere transition region.
In this framework, the Italian High Energy Particle Detector (HEPD) on board CSES-01, is an advanced detector based on a tower of scintillators and a silicon tracker that provide good energy resolution as well as a wide angular acceptance for electrons of 3-100 MeV, protons of 30-200 MeV and light nuclei (up to Oxygen).
The very good capabilities in both detection and discrimination of particles make the detector well suited for space-weather purposes; indeed HEPD is able to continuously monitor the magnetospheric environment with high precision and stability in time. Turbulent conditions in the near-Earth environment translate into modification of particles and magnetic/electric measurements at different time-scales.
In this work, the data-analysis techniques and some preliminary results concerning the study of different proton populations encountered along CSES-01 orbit (galactic cosmic rays, re-entrant albedo etc.) are presented.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
