为了破解北斗应用“走出去”的难题，本文结合卫星导航应用及产业发展的整体趋势，对北斗卫星导航系统（以下简称“北斗”）的服务性能、应用现状进行了总体评估和分析。针对北斗应用“走出去”，分别从系统服务、特色服务、应用产业三个层面上分析了“一带一路”沿线北斗应用推广存在的主要难题，论证说明提升北斗差异化的竞争力是破解北斗“走出去”的重要途径。基于以上分析，针对北斗星基增强和短报文服务，设计两种特色服务在“一带一路”沿线推广应用的初步技术途径和方案。通过在“一带一路”沿线国家设置十多个海外监测站，可满足“一带一路”国家和地区高精度位置服务的绝大部分需求；通过研制建设北斗短报文海外服务系统，可为海量的“一带一路”沿线用户提供性能更优、体验更好的短报文通信服务；针对性给出了北斗特色服务的示范应用推广构想。最后，从政策层面提出了加快推进北斗在“一带一路”沿线国家应用的保障建议。

To solve problems in globalization of the BeiDou Navigation Satellite System (BDS), this paper first analyzes the service performance and application status of the BDS, based on the overall application and development trend of satellite navigation worldwide. Major problems in the application and promotion of the BDS are analyzed from three aspects, including system service, characteristic service, and application industries; and promoting differentiated competitive powers is proved to be effective in assisting the BDS to “go global”. Based on the above analyses, preliminary technical approaches and schemes are designed to promote and apply the satellite-based augmentation and short-message services, two characteristic services of the BDS, along the Belt and Road. By establishing over a dozen of monitoring stations in countries along the Belt and Road, demands of most of these countries for precise positioning can be satisfied. By developing an oversea short-message service system, a short-message communication service, with better performance and experience, can be provided for massive BDS users along the Belt and Road. Promotion ideas for the BDS characteristic services and their demonstration application are also presented. Additionally, some policy suggestions are proposed to accelerate the application of the BDS services in countries along the Belt and Road.
