在反罗兰-C系统工作中,首先要实现各站的时间同步,其次要将目标源信号到达各站的时间参数用无线数传机进行相互交换,再进行比较。目前各站之间是利用搬钟、短波授时、长波授时、电视比对等方法来实现时间同步的。如果能利用无线数传机实现短距离时间传送和同步,就可以克服搬钟的不方便性和电视比对的不随时性。 In the anti-Roland -C system work, we must first achieve the time synchronization of stations, and secondly to the target source signal to reach the station time parameters with wireless data transmission machine for mutual exchange, and then compared. The current station is the use of moving the clock, short-wave grant time, long-wave timing, television comparison methods to achieve time synchronization. If you can use wireless data transmission machine to achieve short-range time to send and synchronize, you can overcome the inconvenience of moving the clock and television non-timely.
