In this paper, we investigate the performance of cooperative deep-space downlink with an amplify-and-forward (AF) backbone relaying in Space-based Information Networks (SBINs). In this SBINs communication scenario, we assume both the source-destination and relay-destination links undergo the shadowed-Rician fading, and the source-relay link follows the Rician fading distributions, respectively. Moreover, the effect of satellite perturbation of backbone relaying satellite is considered, and the maximum ratio combining is implemented at the terrestrial destination. Based on this setup, we first derive the approximate statistical distributions of signal-to-noise ratio of the system, then the closed-form expressions are obtained to efficiently evaluate the outage probability (OP) of the system. Finally, some simulation results are provided to verify our analysis.
