| 摘 要： | 传统全球导航卫星系统（GNSS）接收机基带处理模块非开放式的实现架构与多源融合导航算法的工程实现需求不够匹配，针对机载、弹载的多源融合导航需求设计提出一种开放式的卫星导航基带信号处理方法。通过将卫星导航基带处理模块的软件实现嵌入到Linux 操作系统中，独立运行信号处理进程和底层驱动调度控制，以实现基础的卫星信号捕获、跟踪、时间同步控制等软件功能。硬件实验表明，搭载所述方法的开放式卫星导航基带信号处理系统，可以通过开放式的卫星导航基带信号处理的软件实现，降低多源融合导航实现复杂度。

| Abstract: | The non-open implementation architecture of traditional Global Navigation Satellite System receiver basebandprocessing module does not match well with the engineering implementation requirements of multi-source fusion navigationalgorithms.An open satellite navigation baseband signal processing method for the multi-source fusion navigation requirements isproposed.By embedding the software implementation of the satellite navigation baseband processing module into the Linuxoperating system, the independent signal processing process and underlying driver scheduling control are completed through theembedded system to realize basic software functions such as satellite signal capture, tracking, and time synchronization control.Hardware experiments show that the open satellite navigation baseband signal processing system equipped with the methoddescribed in this paper can be implemented through open satellite navigation baseband signal processing software, reducing thecomplexity of multi-source fusion navigation implementation. |
