基于web技术的探空火箭试验任务可视化设计

为了帮助科研人员理解探空火箭试验任务中获取的抽象数据，直观地了解火箭的飞行状况，本文利用SketchUP创建火箭模型，采用GoogleEarth浏览器插件作为开发平台，利用GoogleEarthAPI驱动火箭模型，直观生动地表达了火箭的姿态、弹道数据。系统采用B／S架构，利用WebSocket前端技术实现了遥测站到web页面的数据传输，解决了传统实时web应用网络实际利用率低下的问题。实验结果表明系统开发部署的成本较低，系统构建的火箭发射场景更为逼真，再现火箭飞行状态的准确性和实时性较好。

A design for sounding rocket visualization system based on web technology

In order to assist Researchers understand the abstract data acquired from the sounding rocket task and know about the flight situation, we model rocket by SketchUP and control the rocket model by Google Earth API. System intuitively expressed rocket ballistic trajectory and attitude in flight. We use WebSocket to transmission data between telemetry station and web page, solved the low network utilization problems of traditional web application. The experimental results show that system development and deployment has a lower cost. System reappear flight situation of sounding has better accuracy and timeliness with a more realistic scenario.
