摘要
随着GNSS-R技术的迅速发展和应用领域的增多,对GNSS-R的多卫星系统的研究显得尤为重要,目前GPS单系统得到了很好的应用,但是GPS单系统不能满足GNSS-R的应用领域,在此发展的趋势下本设计对GPS/BD双系统进行了探索。GNSS-R反演的应用需要导航定位信息提供探测区域接收平台和卫星的详细信息。主要设计完成了GPS/BD双系统定位数据处理软件,包括GPS/BD双系统定位信息的快速接收和数据的正确提取及显示;利用串口通信实现信息的接收及控制命令的发送;可见星星座图显示、状态监控窗口显示和卫星跟踪信息显示等功能;并根据定位数据进行镜面反射点的计算。经过实际工程项目的测试,本软件具有较好的实时性和实用性。
With the rapid development of GNSS-R technology,the research on GNSS-R of multi-satellite system is particularly important.At present,GPS single system has been made great progress.But GPS single system can＇t meet the application of GNSS-R.To solve this problem,GPS/BD dual system is explored.It needs the navigation information to provide detailed information of detection platform and satellite for GNSS-R inversion.Data processing software is designed for the GPS/BD dual system,including receiving location information quickly and extracting and displaying the data accurately,using serial communication to receive information and send control commands,displaying visible star constellation,status monitoring window and satellite tracking information,and calculating specular reflection point.Through testing the actual project,the software has a good real-time performance and practicality.
