I对北斗系统的初步认识和在航海技术上的应用[摘要]作为中国正在实施的自主研发并且独立运行的全球卫星导航系统，北斗卫星导航系统与美国GPS、俄罗斯格洛纳斯、欧盟伽利略系统并称为全球四大卫星导航系统。本文介绍了北斗导航定位系统的发展、组成、工作原理与工作流程。介绍了北斗系统的主要功能及其在航海技术上的应用。北斗系统是一个全天候、区域性的卫星导航定位系统，它的主要功能是利用地球同步卫星为用户提供快速导航定位、简短数字报文通信以及精密授时服务。由于北斗系统不需要其它系统的支持就可以具备通讯与定位的功能，并且融合了卫星增强系统，使其可以更广泛地应用，适合集团大范围地资料获取、监控管理以及用户资料传输，此外北斗系统由我国拥有自主知识产权，因而用起来更加可靠和安全，具有很好的保密性，目前国内的交通运输产业和一些大型企业已经开始逐步装备我国自主研发的北斗卫星导航定位系统。把北斗系统与GPS系统进行了对比，分析了北斗系统的优缺点，并指出了北斗系统的发展与改进方向。[关键词]北斗系统导航通信航海卫星IIAbstract:asChinaisintheimplementationoftheindependentresearchanddevelopmentandindependentoperationoftheglobalsatellitenavigationsystem,beidousatellitenavigationsystemandtheGPS,Russia,theEuropeanUnion,loskenazGalileosystemandcalledglobalfoursatellitenavigationsystem.Thispaperintroducesthedevelopmentofbeidounavigationpositioningsystem,composition,workingprincipleandtheworkingprocess.Introducesthemainfunctionsandbeidousysteminnavigationapplications.Thebigdippersystemisaround-the-clock,regionalsatellitenavigationandpositioningsystem,itsmainfunctionistousegeostationarysatellitesfortheusertoprovidequicknavigationandpositioning,shortmessagecommunicationanddigitalprecisionGPSclockservice.Becausethebigdippersystemsdonotneedthesupportofothersystemscanhavethecommunicationandpositioningofthefunction,andfusionofsatelliteenhancethesystem,makeitscanbemorewidelyused,suitableforgroupbigrangedataacquisition,monitoringmanagementanduserdatatransmission,inadditionthebigdippersysteminourcountrybywithindependentintellectualpropertyrights,andmorereliableandsafeuseup,goodsecrecy,atpresentdomestictransportationindustryandsomelargeenterpriseshavebeguntograduallyequipmentindependentresearchanddevelopmentofourcountrydipperofthesatellitenavigationandpositioningsystem.ThebeidousystemcomparedwithGPSsystem,analyzestheadvantagesanddisadvantagesofbeidousystem,andpointsoutthedevelopmentandimprovementofbeidousystemdirection.Keywords:beidousystemnavigationcommunicationnavigationsatelliteIII目录目录......................................................................................................................................................................III引言.........................................................................................................................................................................1第一章北斗系统简介...........................................................................................................................................21.1北斗系统的概述.................................................................................................................................21.2北斗系统的组成.................................................................................................................................41.3北斗系统与GPS系统的比较.............................................................................................................4第二章北斗系统的主要功能及在航海技术上的应用.......................................................................................62.1北斗系统的主要功能.........................................................................................................................62.2北斗系统的工作原理.........................................................................................................................82.3北斗系统的工作流程.......................................................................................................................102.4北斗系统的主要技术指标:.............................................................................................................102.5北斗系统在航海技术上的应用........................................................................................................112.6北斗系统在航航技术上的渗透........................................................................................................13第三章北斗终端数据处理和应用.....................................................................................................................143.1外设与北斗终端的数据交换与处理...............................................................................................143.2在航标系统中的应用.......................................................................................................................15第四章北斗系统的优缺点及发展建议.............................................................................................................164.1北斗系统的优缺点...........................................................................................................................164.2北斗系统的发展建议.......................................................................................................................17结束语...................................................................................................................................................................18致谢语...................................................................................................................................................................20参考文献...............................................................................................................................................................211引言作为中国正在实施的自主研发
