Abstract

Abstract The paper presents the study of the printed circuit board bus of the autonomous navigation system of a spacecraft using the amplitude criteria based on N-norms. During the study, the authors revealed the most vulnerable places on the bus by calculating the five N-norm profiles along the active conductor of the bus (in 280 segments). The results showed that the peak voltage was reduced by 6.2 % to the end of the active conductor, the signal rate changed sharply but insignificantly (within ±9.3 %) along the active conductor and reduced (by 20 %) towards its end. However, the energy characteristics of the excitation along the active conductor changed insignificantly.
