In order to obtain the relatively high precision of the remote control weapon station, the launch dynamics analysis for small remote control weapon station is carried out. The 3D model of a small remote control weapon station is imported into ADAMS software to simulate the emission dynamics. In ADAMS software, a prototype of the soft-coupled dynamics virtual prototype of a small remote control weapon station is established. In 3 different attitudes, the small remote control weapon station is simulated under 2 different operating conditions, including single and three rounds. The results show that there is a clear relationship between its shooting accuracy and the attitude of the launch, and the larger the pitch angle, the worse the accuracy. This study provides some reference for the design, development and performance evaluation of remote control weapon station.
