随着科技的发展,GPS在越来越多的工程和科学领域得到应用,有关GPS的教学也逐渐引起重视。介绍了用于教学的GPS接收机模拟软件开发。该软件有助于课堂教学和课后学生练习GPS接收机的操作使用。软件采用VC++编程方法实现,接收机各功能的实现基本上采用事件响应函数的形式。运行结果表明,所有GPS定时校频接收机软件前面板模拟结果都与被模拟界面的画面及功能一致,完成GPS接收机的模拟。文中的软件开发方法可为其他教学模拟软件的开发提供参考。
With the development of science and technology,GPS is widely used in more and more fields of science and engineering now,and the GPS teaching is also paid more attention. Analog software development of the GPS receiver applied to teaching is introduced in this paper. The software is not only contribute to teaching GPS receiver in class,but also to the practice to get the equipment operation skill. The software is realized by VC++ programming method,and each function of GPS receiver is realized in the form of event response function. System running results prove that the front panel analog result of GPS timing frequency-adjustment receiver software is same with the picture and function of the simulated interface. The method of software development can provide a reference for development of other teaching analog softwares.
