气象卫星载荷原始数据包快视软件系统开发

为了在气象卫星发射前的整星试验过程中测试各载荷的原始数据包，需要寻找方便快速的原始数据包数据快视方法.首先，介绍了气象卫星载荷原始数据包数据测试基本要求和方法，分析了Matlab在进行低码速率载荷数据包快视软件开发方面的优势；然后，给出了快视软件开发策略和设计流程，并基于Matlab介绍了TCP/IP网口通信、包头查找、数据显示处理的程序编写方法和重点语句；最后，介绍了程序运行速度优化技巧.实践表明，采用Matlab GUI非常适合于卫星研制中的载荷数据快视软件开发. 

Software System Developing of Original Data Packets Quick Display for Meteorological Satellite Payloads

A convenient method is very important to test original data packets of payloads during whole satellite verification test before launching. Firstly, the basic requirements and methods about original data packet test of meteorological satellite payload were introduced. And the advantages were analyzed about developing a quick display software for low bit rate payload based on Matlab. Then, the software developing strategy and process were presented, and many programming methods and codes were introduced based on Matlab about TCP/IP communication, finding packet headers in data, data visualizing and dealing. Finally, some programming skills about elevating program running rate were introduced. The actual running results show that Matlab GUI is very suitable for developing all kinds of data quick display software of payload in satellite engineering.
