In order to achieve rapid establishment of long-distance laser communication links, it is an effective program to adopt a GPS / INS integrated navigation system (GINS) for completing the initial pointing of the dynamic laser communication. Firstly, we present a dynamic initial pointing algorithm (DIPA), which can be applied to get the pointing angle (PA) by calculating the real-time data received from GINS. Next, the feasibility of the pointing system is analyzed and the hardware system as well as PC software is designed. Then, experiments in the outdoor are carried out to prove the DIPA. Finally, the correctness and reliability of the pointing system is analyzed.
