摘要

利用动态精密单点定位技术,分析了日本仙台大地震对日本及中国境内若干GPS基准台站的影响。结果表明,采用动态精密单点定位技术能准确地反映GPS台站的受损程度,有效地探测地震发生时刻及其震后位移。
Based on kinematic precise point positioning(PPP) technology,the influence of Sendai Earthquake(in Japan) on GPS reference stations is analyzed.For three IGS tracking stations located respectively in Japan and Chinese,kinematic resolution is carried out.Results show that the extent of damage of these GPS stations can be implied according to kinematic PPP technology.Besides,earthquake occurrence time and post-earthquake displacement can also be effectively detected according to station coordinates,velocity,and their change information.On the basis of analysis on post-earthquake displacement,stations such as MIZU and TSK2 have been damaged seriously,while those in China are remaining unaffected with relative stability.
