中文摘要： 现今，GPS及信息技术发展迅猛，在我国的物流、定位、交通安全等领域尤为普遍。而利用国外卫星导航系统资源对我国许多领域具有很大的风险性，不能满足我国对信息、交通安全的要求。铁路运输具有运输能力强、速度快、网络覆盖广等特点，其运输的货物有多种，如党政公文、军事物资、大件物品、冷藏物品、危险品、能源、贵重金属、专利设备等。这些高附加值货物关系到国家政治、军事以及企业、百姓等广泛利益，提高铁路系统运输安全和能力，有效管理铁路高附加值货物运输成为我国经济和社会发展中日趋紧迫的任务。我国北斗卫星导航系统已正式对亚太地区提供连续无源定位、导航、授时等服务，这为我国军用和民用领域以及经济和社会发展提供安全、高质量通信服务成为现实。 随着我国高速铁路的快速发展，在铁路运输方面亟待需要解决安全有效的铁路货运列车定位问题。本项目将利用北斗卫星导航系统结合相关理论研究铁路货运列车北斗定位模型、算法及关键技术。

英文摘要： The railway transport is the transportation system with the strong capacity of national passengers and freight transport as well as the wide network coverage. There are a variety of such highly-added value freights in the railway system transportation as government archives, military commodity, big-ticket items, refrigerated items, dangerous materials, energy, rare metals, patent equipments and something like that. The highly-added value freights are related to the interests of national politics, military as well as corporate besides the populace. It is dramatically urgent in China's economic and social development to improve supplies transport capacities and service levels in the railway system and to strengthen the management of railway transport of goods with highly-added value. Satellite tracking technologies have been employed to guarantee important freight transportation in Europe and the United States. BeiDou（COMPASS）Navigation Satellite System will guarantee important freight transportation in China. At present, it is difficult to modify the existing railway goods equipments and vehicles; in addition, logistics information is at low level. Hence, it is beneficial to develop the railway intelligent tracking system in connection with high-value-added goods, to save up social resources and to improve management level concerning the logistics information in terms of promoting China's economic and social development.Study on BeiDou Positioning Model,Algorithm and Key Technology of Railway Freight Train
