| 摘 要： | 讨论了多路径效应对GPS共视比对的影响及削弱其影响的方法。结合综合原子时项目的需求,研制了适用于单频GPS接收机的天线扼流圈,并用零基线比对方法进行了测试。结果表明,研制的天线扼流圈可有效地削弱多路径效应的影响,并可明显地改善单频GPS接收机NTSCGPS-1的抗干扰能力。

| Abstract: | The effects of multipath on GPS Common-view comparison and the metheds of reducing the effects are discussed.An antenna choke ring suitable to the single frequency GPS receiver was developed,in which the demands of JATC(joint atomic time of china) were taken into consideration,and the choke ring has been tested with the method of zero-line comparison.The results show that the developed antenna choke ring can effectively reduce the multi-path effects and can improve the interference-resistant ability of the single frequency GPS receiver,NTSCGPS-1. |
