A statistical comparison of failures on geosynchronous satellites in the maximum and during the decline of the 22nd solar cycle (1989–1994) with space weather parameters is carried out. A positive correlation of the rate of failures with the flux of relativistic electrons on the geosynchronous orbit and with the proton flux measured before the bow shock front is revealed. The significant positive correlation of the electron flux with the rate of failures is observed during the entire considered interval. The correlation coefficient varies in the solar activity cycle in coordination with the electron flux, and the maxima of the correlation coefficient are observed on the phase of decline of the cycle. A statistically significant positive correlation between the flux of protons with energy of more than 1 MeV and the rate of failures is revealed in the maximum of the solar cycle.
