| 摘 要： | 利用可编程片上系统(SOPC)技术,设计了一种基于FPGA的GPS接收机。提出了基于多普勒频域移位的捕获策略,并分析了捕获时间。基于延迟锁定环与Costas环跟踪方法,给出接收机的SOPC实现。实验结果表明,该接收机的信号捕获、跟踪方法正确可行,且在静态条件下水平定位精度优于4.5m(标准差),具有良好的实时性、灵活性和可扩展性。 |

| Abstract: | A GPS receiver based on FPGA was designed using SOPC technology.An acquisition strategy based on Doppler Shifting was proposed and acquisition time was analyzed.Using delay lock and Costas tracking approaches,a GPS receiver was implemented in SOPC.Experimental results showed that signal acquisition and tracking modules of the receiver functioned properly;and in static conditions,horizontal positioning precision was better than 4.5 m(Std Dev).The design on the whole is satisfactory in real time operation and... |
