BD2/GPS信息采集与处理系统的研究

摘要

At present,BD2 satellite navigation and positioning system is capable of regional navigation.BD2/GPS receiver based on dual-system positioning system was studied.The communication protocol and sentence of BD2/GPS was discussed.wBD2/GPS data acquisition method was discussed between computer and BD2/GPS receiver in detail.The flow of software design based on VC++ was also presented.The positioning performance parameters of BD2/GPS receiver were analized.The positioning system setting of BD2/GPS receiver was realized.Experiment test results indicate that the system works stably,has friendly interface and better expansibility.The system can be used for the positioning performance analysis of BD2/GPS system receiver.%我国自主研制的北斗二代卫星导航定位系统已具备区域导航定位的能力,文中以BD2/GPS双系统导航接收机为研究对象,研究BD2/GPS双系统接收机的通信协议,给出BD2/GPS双系统接收机的数据采集方法,详细设计了基于VC++的BD2/GPS接收机信息处理与分析软件,并给出其软件流程,研究了接收机定位性能的评价指标,并提取BD2/GPS联合定位时的状态参数以及精度因子.同时,实现了计算机对BD2/GPS双系统接收机的设置与控制.通过实际测试和调试表明:设计的BD2/GPS接收机信息采集与处理系统工作稳定,界面友好,扩展性强,可用于对BD2/GPS双系统接收机定位性能进行分析.
