In order to evaluate the effect of pointing error on space chaos laser communication system, we conduct bit error rate (BER) analysis with external mismatch and internal mismatch caused by pointing error. Based on BER formulae, numerical simulations are conducted to investigate the effect of external and internal mismatches on performance of the system under different boresight and jitter. Our results indicate that jitter will affect BER more than boresight and internal mismatch will affect the performance of system more than external mismatch. These results are significant for optimizing space chaos laser communication system design.
