摘　　要：北斗时间频率系统(简称时频系统)是我国独立建设和维护的时间频率系统。北斗星载时频系统是北斗时频系统的重要组成部分。以北斗星载时间频率系统的发展建设为主线,综合各类国内外文献、网站发布的技术管理信息,梳理了北斗星载时频系统的发展历程,描述了当前以星载时频系统为主的北斗时频系统的现状,并在分析归纳当前系统状态的基础上,提出了未来北斗星载时频系统的发展趋势。BeiDou Time ＆ Frequency System（BDTFS）are built and maintained by China independently. BeiDou on-board time ＆ frequency system are the important parts of BDTFS. This paper follows the main building route of BeiDou on-board time ＆ frequency system based on the technical information from various references and wehsite. It introduces the development milestones and current states of Beidou on-board time ＆ frequency system. Finally, its future technical prospects are suggested.
