BPM短波授时信号模拟器的研制

A BPM Short-wave Time-service Signal Simulator

介绍了BPM短波授时信号模拟器的主要功能和工作原理,阐述了该模拟器的系统组成、输入输出及软件流程。该模拟器以GPS信号作为时间源,以10 MHz的高稳定恒温晶振作为守时频率源,并在程序控制下产生载频与调制信号,放大输出6路BPM短波模拟信号。测试结果表明,该模拟器的功能与技术指标符合BPM短波授时信号的要求。

The main function and principle of a BPM short-wave time-service signal simulator is introduced.The components,input/output interfaces and software flow chart for this simulator are expounded.The clock of time-keeping of the simulator,whose time source is traced to GPS,is driven by a 10 MHz OCXO,a cryetal oscillator with high stability and constant temperature.The simulator produces the carrier frequency and modulating signal under the program control,and provides 6 channels of amplified BPM signals.Some tests indicate that the technical indexes of this BPM signal simulator meet the demand of BPM short-wave time-service signal.
