摘　　要：基于STK和STK/Connect模块构建了卫星实时仿真系统框架。以VC＋＋6.0为平台开发了卫星实时视景仿真软件,并详细给出了VC和STK集成、仿真数据的发送解析、仿真时间同步等关键技术的实现步骤。该软件利用UDP/IP协议接收数值仿真机广播的卫星仿真数据并进行解析,通过STK/Connect模块发送指令,实时驱动STK进行二维和三维视景渲染,实现了卫星在轨运行状态的实时视景显示。A framework of realtime satellite simulation system is constructed based on STK and STK/Connect module and realtime visualization satellite simulation software is developed based on VC＋＋6.0.Approaches for integrating VC with STK,sending and translation of simulation data and synchronization of simulation time are presented in detail.Using UDP/IP protocol,the software receives data broadcasts from a numerical simulation computer,translates it into STK commands and then sends the commands to STK with the Connect module to drive STK to draw 2D and 3D scenes in realtime.The result shows that the software realizes realtime visualization simulation of satellites.
