中文摘要： 定位导航是人类对自然认知的最基本的要素之一，它对我们的生活方式、社会及国家的安全保障都有着及其重要的意义。然而，尽管目前有多种定位技术在应用或研究，但都有着各自不同的局限性，如何实现真正意义的无缝定位及在恶劣环境下如何进行协作导航，仍然是该领域研究者共同面对的难题。本项目拟在前人的研究基础上，结合认知网络下的节点认知特性和节点相互协作的特性，探讨传统的定位终端在具备自适应感知和相互协作的能力后，对传统的无缝定位思想带来的重要改变，同时为协作网络导航的实际应用提供技术支撑。具体内容如下：①建立基于终端的定位精度自适应模型，规避传统数据融合技术的高复杂性，为各种定位技术的有效融合提供理论支撑；②认知网络下，探讨节点相互协作的模型及其策略分析，针对典型场景进行重点应用研究，为网络节点协作导航提供理论基础；③确认协作模型及策略后，建立基于时间和空间协作的组合滤波模型，并对其进行优化分析。

英文摘要： Positioning and Navigation is one of the most basic elements about nature awareness for human, and have very great significance on our lifestyle, social and national security. However, although multiple positioning technologies were applied and researched, they all have their different limitations. How to realize the real seamless positioning and collaborative navigation in harsh environment are still the common challenge for researchers in this field. According to previous research foundation, the project intends to combine the cognitive characteristic of node and the collaborative performance among nodes in cognitive network, and explores the huge innovation for traditional positioning technology when traditional positioning terminal are able to aware nature adaptively and collaborate each other. Therefore, these studies can provide technical support for the practical application on collaborative network navigation. The specific contents are as follows: (i)The accuracy-adaptive model would be designed based on terminal for avoiding the high complexity of traditional data fusion technology and providing effective theory support for different positioning technology;(ii) we would explore the collaborative model among nodes and analyze their collaborative strategies, then focus on some of the typical scenarios for application;(ⅲ)After determining collaborative models and strategies, we look forward to designing the hybrid filter model based on time and space, and conducting performance analysis and model optimization.
