Paper Abstract

The influence of burst errors on a satellite-borne, free space optical communication systan is evaluated. Burst errors occur when the instantaneous mispoint loss exceeds the allocation in the link budget. The single axis mispoint probability distribution is described as a gaussian function and used to define the probability of burst error. It is shown that the probability is related to the ratio of the pointing error and the rms standard deviation of the pointing error distribution. It is also shown that an optimum ratio of the beam-width to the pointing error may be deduced from the range ecuation. A relationship between the rms standard deviation of the pointing error distribution, the probability of burst error and the Airy far field beamwidth has been derived. The limitations caused by mispointing and the probability of burst error on the systan beamwidth and the antenna diameter are discussed. It is shown that a satellite-borne optical camiunication system must include both the probability of bit error and the probability of burst error for system requirements to be adequately specified.
