摘　　要：影响卫星无线电测定业务接收机工作性能的指标有很多,其中对测距精度有影响的主要是接收机的双向零值,因此建立一套准确的测定双向零值方法是必要的。本文首先介绍了RDSS工作原理,通过分析产生双向零值的原因,提出了一种接收机双向零值的测试方法,即在实验室工作环境下构建RDSS仿真环境,利用仿真数据和观测数据对接收机双向零值进行求解,并对结果进行评估,结果表明该方法可以用于接收机双向零值的测试。There are many indicators influencing the performance of RDSS （Radio Determination Satellite Service） receiver, among which two-way zero value is a main factor deciding a receiver＇s ranging accuracy. It is necessary to establish an accurate test method to test the two-way zero value. This thesis first introduced how RDSS works, then generated a test method on two-way receiver zero value by analyzing the production causes of the two-way zero values. In particular, a RDSS simulation environment was built under laboratory environment, and two-way zero value was derived and evaluated by using the simulation data and the observational data. The results showed that this method would be feasible in testing the two-way zero value.
