摘　　要：针对平原地震发生后,可能造成的区域坐标参考框架变化,本文选取了震中周边7座山东省北斗卫星导航定位基准站,利用其高采样率GNSS数据,结合快速星历与快速钟差等产品,使用PRIDE PPP-AR软件,通过精密单点定位技术,对数据进行解算与分析,对地震可能造成的区域坐标参考框架变化做出了快速响应。实验结果表明:震中周边的基准站均未发现位移突变,此次地震未对区域坐标参考框架造成破坏,山东省北斗卫星导航定位基准站网可以为震后救援及重建提供测绘基准服务。After the Pingyuan earthquake,in view of the possible changes in the regional coordinate reference frame caused by the earthquake,this paper selected 7 Beidou satellite navigation and positioning reference stations in Shandong Province around the epicenter,used their high-frequency GNSS data,combined with products such as fast ephemeris and fast clock difference,and used PRIDE PPP-AR software to solve and analyze the data through precision single point positioning technology.Rapid response is made to the possible changes of regional coordinate reference frame caused by earthquakes.The experimental results show that no abrupt change was found in the displacement of reference stations around the epicenter,and no damage was caused to the regional coordinate reference frame.The Shandong Beidou satellite navigation and positioning reference station network can provide mapping reference services for post-earthquake rescue and reconstruction.
