摘要： 长波授时系统是目前国际上授时精度较高的大型地基无线电授时服务系统，其授时信号采用罗兰C信号发播体制，具有作用距离远、稳定性好、可靠性高、抗干扰能力强等优点。针对GNSS信号在某些特定区域易被干扰、易失锁的问题，设计并实现了一种长河二号授时监测接收机，采用信号完好性检测、ASF（附加二次相位因子）时延修正等技术，实现了高精度、高可靠长波授时与时差监测，可作为GNSS授时的重要补充手段。

Abstract: The long wave timing system is a large ground-based radio timing service system with high timing accuracy in the world at present.Its timing signal adopts the transmission system of loran C signal,which has the advantages of long distance,good stability,high reliability and strong anti-interference ability.For GNSS signals in certain areas vulnerable to interference,volatile lock,designs and realizes a kind of changhe No.2 timing monitoring receiver,the signal integrity test,the ASF(additional quadratic phase factor)delay correction technology,and realized the high precision,high reliability and long time monitoring,can be used as an important supplement to the GNSS timing means.

Key words: Changhe No.2, Loran C, Long wave timing, Timing monitoring
