Abstract: With the rapid development of military intelligence, traditional combat training urgently needs to use intelligent technology for mission planning and virtual combat simulation. Based on a portable Android device, this paper develops a high-speed target mission planning software for target missiles, uses JNI technology to achieve rapid calculation of trajectories and firing tables, and realizes the graphics of target points, landing points, and launching azimuths through OSMDroid. Based on VR-Forces, a virtual simulation system for target missiles with good visual immersion and interactivity is constructed for the simulation and evaluation of mission planning results. The experiment results show that the system can complete mission planning and simulation conveniently and efficiently, and improve the efficiency of target missile training.
