In this paper, we analyze the outage probability of the radio over intersatellite optical wireless communication system in the presence of satellite vibration with bias error. The lower-based Mach–Zehnder modulator, optical booster amplifier and optical preamplifier are employed. First, the models of the proposed system and channel are given. Then the outage probability for a given bit error ratio (BER) of a quadrature phase shift keying signal is obtained in the presence of satellite vibration with bias error. Numerical results of outage probability with different bias error and average BER are given. Results indicate that the outage probability is obviously influenced by the pointing error and the optimum telescope diameter to minimize the outage probability exists. With the same pointing error condition, the value of the optimal telescope diameter will increase with the reduction of the given average BER.
