摘　　要：为分析1000kV特高压输电线路对中波航空导航台的无线电干扰情况,在国家电网特高压交流试验基地进行了飞行试验。利用机载全球卫星定位导航系统(global positioning system,GPS)和地面GPS连续采集直升机穿越特高压线路的飞行数据,采用精密单点定位技术确定飞机航迹,并与理论航迹进行比较。试验结果表明:1000kV特高压线路对中波航空导航台无线电的干扰与飞机距离特高压线路的远近和飞机飞行高度没有明显关系。To analyze the 1 000 kV transmission line-caused radio interference in non-directional beacon, the flight test was carried out in UHVAC base of State Grid Co. The consecutive collection of flight data under the condition that the helicopter passed through UHV transmission line was implemented by airborne global positioning system （GPS） and ground-based GPS; the helicopter＇s track is determined by precise point positioning technique and compared with theoretical flight path. Test results show that there is no distinct regularity between radio interference from UHV transmission line and the flight height of helicopter and there is also no distinct regularity between radio interference from UHV transmission line and the distance from the helicopter to UHV transmission line.
