【摘要】 结合多模卫星导航信号自身的特点以及功能需求,按照模块化的设计思想进行功能划分,以模块功能为单元组成多模导航信号捕获系统。通过对软件的体系结构设计,以及系统重组中的关键技术问题的实现,设计了模块级的可重组多模导航信号捕获系统,实现了各个软件模块间的数据交换、任务调度、资源分配、协同处理等,同传统的多模导航信号系统相比,该系统具有更好的兼容性、可靠性及灵活性。更多还原

【Abstract】 Based on the characteristics and functions of multi-constellation satellite navigation signal,the module of acquisition algorithm of navigation signal is classified in this paper according to modularization idea.The realization of acquisition algorithm system is configured in terms of module units.Then we designed a reconfigurable multi-constellation satellite navigation signal acquisition system based on modules through studying the software architecture and the key problems in dynamic reconfiguration system.This system realized the data-exchange,task scheduling,resource-distribution and cooperated processing between the software modules.Compared with traditional system for multi-constellation satellite navigation system,this system is more compatible,reliable and flexible.更多还原
