| 摘 要： | 在分析强震地震波信号幅频特性的基础上，采用GNSS信号模拟器，设计具有强震地震波特点的正弦轨迹，从载波相位原始量测数据和定位结果两个层面分别评估两款GNSS接收机（Trimble Net-R9和NovAtel OEM628）高频（50 Hz）观测的测量性能。结果表明，在地震波高频动态条件下，两款接收机的载波相位和定位结果都出现了明显误差，测量精度随正弦运动频率的增加而恶化，Trimble Net-R9接收机尤甚。

| Abstract: | In this paper, we conduct analysis of signal amplitude-frequency characteristics of strong seismic waves. Based on this analysis, sinusoidal strong seismic waves are generated by a GNSS signal simulator. Moreover, the performance of high-rate (50 Hz) GNSS observations collected by two GNSS receivers (Trimble Net-R9 and NovAtel OEM628) are evaluated from the aspects of raw carrier phase observations and positioning results, respectively. The results show a significant error in both carrier phase and positioning results, in the case of high-frequency motion. Furthermore, the measuring accuracy of two GNSS receivers, especially the Trimble Net-R9, deteriorates with the increase of the frequency of sinusoidal seismic wave. |
