摘要

干扰是指干扰电子仪器设备或通信工具功能的电磁辐射或反射。有意破坏或干扰用于定位、导航和授时的GPS信号,称为“GPS干扰”,是使用射频发射装置完成的。2022年1月8日(北约演习当天),研究了GPS信号干扰如何影响冰岛三个IGS点的定位精度。得到的MAYV、HOFN站运动处理与静态处理的坐标差值约为0.5 ~ 10m。除冰岛GPS信号干扰效应外,本研究冰岛三个IGS站22年(2000-2022年)的水平和垂直速度场。根据得到的结果,在冰岛的三个IGS观测站(HOFN、REYK和MAYV)上计算了大约2cm-2.5cm /年(水平)和0.1cm-2.1cm /年(垂直)的运动。

Monitoring of Icelandic plate movement with GNSS method and GPS signal jamming effects in Iceland
Abstract Jamming is electromagnetic radiation or reflection that impairs the function of electronic instruments and equipment or communication tools. Intentionally disrupting or interfering with GPS signals, which are used for positioning, navigation, and timing, known as “GPS jamming”, is accomplished using a radio frequency emitting device. On January 8, 2022 (the day of a NATO exercise), it was investigated how GPS signal jamming affected the position accuracy at three IGS points in Iceland. The obtained coordinate differences between kinematic processing and static processing reached values of about 0.5–10 meters for the MAYV, and HOFN stations in this study. In addition to GPS signal jamming effect in Iceland, horizontal and vertical velocity fields of the three IGS stations in Iceland covering a twenty-two year period (2000–2022) in this study. According to the obtained results, a motion of about 2cm–2.5cm per year (horizontal) and 0.1cm–2.1cm per year (vertical) was computed at the three IGS stations (HOFN, REYK, and MAYV) located in Iceland.
