摘　　要：利用单频载波相位平滑伪距差分技术可对动态目标进行实时监控,不需要价格相对较贵的双频接收机即可满足工程需要。给出了单频GPS和载波相位平滑的伪距差分定位数学模型,采用C++语言开发了相应的程序模块。对某湖水上动态目标的监测试验,验证了程序模块的正确性,数据处理分析结果表明,相比伪距差分定位,采用载波相位平滑伪距差分技术监测动态目标应用效果较好,可获得分米级精度的水上动态目标监测。Single-frequency carrier phase smoothing pseudor- ange differenced technology can be used to monitor dynamic ob- jects. This technology can satisfy engineering requirement with- out double-frequency receiver which relatively expensive. The paper describes the math models for positioning using single fre- quency GPS and carrier phase smoothing pseudorange differ- ence with C＋＋ language compiling the software part. Based on the test about monitoring the dynamic object on a lake, the soft- ware part can be verified correctly. The data analysis result in- dicates, compared with pseudorange difference positioning, car- rier phase smoothing pseudorange difference positioning can reach a better effect when monitoring dynamic objects. It can reach decimeter level positioning precision in the water dynam- ic objects monitoring
