摘　　要：由于卫星导航信号强度弱易被干扰,可以通过人为手段(如GPS的SA)播发欺骗信息,使海上船只的导航信号容易被干扰、蒙蔽和控制。通过对星基导航完好性监测方法的探讨,介绍了通过建立一个卫星导航系统信息源完好性监测数据库,并利用地球同步卫星,将监测结果实时地传输到监控中心,来建立一套可靠性高、实时性强的海上卫星导航信息源完好性监测系统,解决我国海上特殊用户星基导航可靠性保障的问题。Because the satellite navigation signal is easily interfered, the sea boats and ships are interfered,hoodwinked and controlled by means of emitting the fraudulent signal. The methods of integrity monitoring of the satellite navigation is discussed. The integrity monitoring database of a satellite navigation system signal source built, and the monitor results transferred to the monitoring center, so a high credible and real time monitor system of the satellite navigation signal soruce on the ocean can be built, in order to resolve the problem of a dependable guarantee of our country satellite navigation on ocean for special user.
