摘　　要：设计了一种基于北斗短报文的卫星导航信号区域监测系统,可实现对指定区域卫星导航系统的持续全天候监测。针对北斗短报文可靠性和通信容量有限的特点,提出了一种带反馈重发机制的多卡自适应发送方法,可明显提高发送效率和可靠性。研究了一种多站联合干扰源交汇定位算法,并设计了导航信号区域完好性监测方法,可在出现异常时对干扰源进行定位并及时告警,具有较强的实用价值。A satellite navigation signal regional monitoring system based on BDS short message is designed,which can realize the continuous all-weather monitoring of the satellite navigation system in the designated area.In view of the limited reliability and communication capacity of Beidou short message,a multi-card adaptive sending method with feedback retransmission mechanism is proposed,which can obviously improve the sending efficiency and reliability.A multi-station joint interference source intersection location algorithm is studied and a navigation signal area integrity monitoring method is designed,which can locate the interference source and timely alarm when abnormal,which has strong practical value.
