利用机载GPS监测特高压输电线路对航空飞行的干扰

Interference Analysis to Aerial Flight Caused by UHV Lines Using Airborne GPS

采用机载GPS监测特高压输电线路对航空飞行可能产生的干扰,并进行干扰程度分析。在直升机上安装高精度GPS定位系统,对飞行轨迹进行连续数据采集。数据处理和分析表明,航线偏离值的大小与距离特高压线路的远近没有呈现明显规律性,与距离特高压线路的远近无关。

Using airborne GPS monitors,we analyzes the interferences to aerial flight caused by ultra high voltage （UHV） lines. The continuous flight track data was collected by GPS installed in a helicopter. The methodology of data processing and analysis was studied. No regularity appears between the discrepancies and distances of UHV lines. Some conclusions and suggestions are drawn to the protecting distance of UHV lines to the aeronautical radio navigation station.
