摘　　要：利用trackRT实时定位模块对GPS连续站数据进行处理,得到测站的实时动态位移,精度水平方向约为1 cm、垂向约为2 cm;利用其RINEX模拟模块trackRTr对2011年日本Mw9.0地震的1 Hz GPS数据进行模拟实时处理,与事后处理结果较为一致;分析卫星轨道星历和基线长度对解算精度的影响,结果表明基线长度对解算精度影响较大。Real-time dynamic displacement of the stations was obtained by using trackRT real-time positioning module to process continuous GPS data, the horizontal accuracy is about 1 cm, vertical accuracy is about 2 cm; trackRTr was also used to process 1 Hz GPS data of 2011 Japan Mw9. 0 earthquake to simulate real-time processing and a comparison with post-processing was made; the impact of ephemeris and baseline length on accuracy was also analyzed, the results show that the baseline length plays a important role on the calculation accuracy.
