摘要
介绍了无线通讯方式传递时间的手段和准确度。以GPS系统为例,论述了一种多站点精确时间同步方案,阐述了该方案中所运用GPS授时终端的设计原理。对时间同步准确度进行了分析,该方案的时间同步准确度优于50ns。本文虽以GPS系统为例,但对于其他系统的类似运用也有借鉴意义。
The method and accuracy of time transfer are introduced in radio communication. Regarding GPS as the example a kind of project for multi-station exact time synchronization is discussed; design of the GPS time transfer terminal is expatiated in this project. Time synchronization accuracy is analyzed; it is better than 50ns in this project. This text although regarding GPS system as the example, but the similar application of other system also has to draw lessons from the meaning.
