The technological CubeSat VZLUSAT‐1 was launched in June 2017, and carries a number of scientific and commercial experiments aboard. Several of them are focused on in‐orbit investigation of a novel carbon‐fiber composite developed by the 5 M company; examination of residual liquid evaporation, change of eigenfrequencies of the material due to aging, and shielding abilities against cosmic radiation. The quality of shielding is evaluated from a comparative measurement between three channels with different shielding. Each channel contains a calibrated biased PIN (p‐type, intrinsic, n‐type semiconductor regions) diode as the radiation sensor, which is sensitive to radiation in the 6–80 keV energy range. Preliminary results from the in‐orbit measurements are presented in this paper.
