【摘要】 为了提高全球卫星导航系统服务的连续性、可靠性与完好性,进行导航增强是常用手段之一。本文首次提出了志愿者卫星导航增强的相关概念,分析了志愿者导航增强的组成要素与拓扑结构。重点研究了志愿者及普通用户利用现代通信信息网络进行自组织信息交换的神经网络模型,特别研究并建立了利用共享信息进行志愿者导航增强的神经元模型,从而进行交互式广义相对定位,构建了志愿者导航增强的基本理论与方法。在此基础上,深入研究了志愿者导航增强方式与方法的实现机理,形成了相对较为完整的志愿者导航增强体系架构。通过本文的研究,形成并构建了一种集用户所需信息(含导航增强信息)交换与导航定位服务于一体的、用户自助式的卫星导航增强方法与机理,有利于解决导航系统服务的连续性、可靠性与完好性问题。本文提出的志愿者导航增强的思想,突破了卫星导航的传统应用模式,拓展了卫星导航增强方式的内涵与外延。更多还原

【Abstract】 Navigation augmentation is a common method for the purpose of the continuity improvement,reliability advancement and integrality enhancement in satellite navigation system.Based on the widely application of satellite navigation system and the rapid development of modern communication technology and network technology,the idea of volunteer augmentation navigation technology is offered and discussed in this paper.The basic definition is that based on the basal services offered by satellite navigation system providers and navigation application providers,let navigation users and information providers be the "volunteers".According to the standard criterion,and using the modern communication technology and the network technology to act information exchange or alternant face to face positioning,the volunteers are combined to a flexible and convenient navigation service sharing set.A discussion to volunteer augmentation navigation technology is given in this paper,consequently the "denseness augmentation" and "sparseness augmentation" is compared.In the end,the conclusion shows the working principle and the essential frame of volunteer augmentation navigation.更多还原
