摘要
利用CsSync 1 0 0 0型接收机的输出数据 ,分析了BPL信号在接收点的质量 ,还将该接收机的GRI与主钟 (CSAO) 1PPS比较 ,给出了接收时间内BPL发射系统时延变化范围。分析结果表明 ,BPL发播控制具有较好的短期和中期稳定性能。为进一步提高发播时间控制的稳定性 。
The equality of BPL signal at the receiving point is analyzed based on the output data from the serial port of Cs Sync 1000 receiver system;Similarly,the delay fluctuation for BPL transmitting system can be found by comparing the GRI pulse with the 1PPS of master clock for CSAO. The result shows that the BPL transmitter system has good stability in short and medium terms. New control method and equipments are necessary in order to improve the stability of the emitting time.
