采用程序集技术的卫星数据解析软件设计

卫星实时定位和事后数据精度分析中,不同厂家的卫星接收机经常一起使用,同一种类数据帧格式彼此不同,甚至同一厂家、不同型号的卫星接收机数据格式也经常变化,这给数据解析带来很大不便。本文在卫星接收机数据解析软件中采用面向对象的设计方法,利用UML（统一建模语言）进行建模,针对数据格式经常变化的情况采用数据库预定义技术,最后通过.Net程序集技术实现了不改变软件代码即可适应新的卫星接收机数据格式的目标。实际应用证明,该软件具有结构直观、处理数据种类多、可扩展性强等特点,在卫星数据解析的通用性方面做了有益的尝试。

Design of Analytical Software for Satellite Data Based on .Net Procedures

Satellite receivers of different companies are often used at the same time in realtime satellite positioning and post-mission analysis of data accuracy. Most frame formats of the same type of data are different. Even the data formats of satellite receivers of different models of the same company often change. This brings a lot of inconven- ience to data analysis. Therefore, object oriented design method is used in analytical software for data of satellite re- ceivers. UML （Unified Modeling Language） is used in modeling and advance definition teehnology of database is used to deal with changes of data formats. Meanwhile, . Net Procedures technology is used to adapt to new data for-mats of satellite receivers without change of software codes. Practical application shows that the software features straightforward man-machine interface, handling of numerous data types and high scalability.
