Abstract: 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.
