Abstract
Digital satellite communication links are usually characterized by transmission capacity, link distance, bit error rate, availability and lifetime. For optical data links however an additional parameter, the burst error rate has to be specified. The physical reason for occurence of burst errors lies in the required precise mutual tracking of both satellite communication terminals. The influence of the statistical motion of both satellites around their nominal attitude on optical data link performance has been studied by computer simulations. Improvements achievable with forward error correcting coding are analysed. These simulation results are based on a Gaussian distribution of indenpendently vibrating satellites. Realistic values for simulation are obtained by multiplication with the Fourier transform of complex transfer function of spacecraft motion.
