| 摘 要： | 航天测量船时间统一系统时间信号经SDH通道传输后出现抖动和突变现象。以时间统一系统SP通道传输的时间信号为基准,对SDH通道的传输时延进行了精确测量,得到了时延分布、抖动和突变情况,结合SDH通道传输业务的机理、过程和时延特性分析了产生时延抖动和突变的原因,为改进SDH通道传输性能提供依据。

| Abstract: | The time-uniform system signal was oscillated and break by SDH channel on the TT&C ship.Taking the standard of time signal transmitted from SP channel,the signal from SDH channel was measured,and the distribution of time delay can be found.The reasons of producing oscillations and break in time delay with the mechanism of SDH transmission scheme are analyzed,the basis for improving the performance of SDH channel is provided. |
