    Abstract
  • In order to study the impact of  strong electromagnetic environment of the substation on performance of the GNSS receiver and quality of observation data,GNSS receivers were arranged on the roof of main control building of the 500 kV, 220 kV and 110 kV substation respectively to observe continuously for 24 hours. The impact of substation on performance of the GNSS receiver and the quality of the observation data is comprehensively evaluated through internal noise of the receiver,data integrity rate, signal-to-noise ratio, and multipath effects. The experimental results show that the GNSS receiver can work normally under strong electromagnetic environment of the substation, and the substation does’t have significant impact on quality of observation data.The quality of observation data meets the corresponding standards.
