摘　　要：对民丰卫星地震台站台址勘选和建设过程进行回顾,其中:①在台站勘选过程中,使用EDAS-24IP数据采集器和短周期地震计CMG-40T-1进行数据记录,分析认为,拟选台址达Ⅰ类台基噪声水平,且所在地区阳光充足,干扰源较少,适合建设地震台站。②在台站建设过程中,依据相关规范建设其主体结构,并充分考虑太阳能供电系统以及设备和数据安全等因素,采用卫星通信方式进行数据传输。③台站建成后,重新计算台基背景噪声RMS值及功率谱密度,确定台基噪声水平为Ⅰ类。台站试运行期间进行仪器标定,脉冲与正弦标定波形良好,符合标定要求。The survey,selection,and construction process of Minfeng Satellite Seismic Station were reviewed,in which:①In station exploration and selection,the EDAS-24IP data collector and short-period seismometer CMG-40T-1 were used for data recording.The analysis showed that the proposed station site reached class I station base noise level and the area was sunny with fewerinterference sources,which was suitable for the construction of seismic stations.②During the construction of the station,the main structure is constructed according to the relevant specifications,the solar power supply system,equipment,data security,and other factors are fully considered,and the satellite communication mode is adopted for data transmission.③After the station is completed,the RMS value and power spectral density of the background noise at the station base are recalculated,and the noise level at the station base is determined to be class I.During the trial operation of the station,the instrument was calibrated.The pulse and sine calibration waveforms were good and met the calibration requirements.
