摘　　要：根据当前空间科学探测的特点,针对探测任务设计运行阶段的仿真和显示需求,提炼了三种典型的态势元素并进行了二维可视化算法及效果研究。设计了一个通用的二维态势显示系统,能对实时遥测数据或者模拟数据进行分析计算,解决了实现中的细节分层和地图漫游等技术难点。基于VC++和Direct3D语言开发,运行结果表明,系统具有很好的通用性和执行效率。To fulfill the simulation and display requirements during missions＇ design and execution phase,three typical situation elements were abstracted based on the present space probe characteristics.Also,research was done on 2D visualization algorithms and effects.Moreover,a general 2D situation display system was designed which can calculate and analyze real-time telemetry data as well as simulated data.During the development of this display system which is implemented in VC ＋＋ and Direct3D,problems in level of detail and map roaming were solved.The execution result proved that the system is of good universality and efficiency.
