GNSS技术在地震监测预报等方面具有非常良好的应用空间。本文从GNSS技术的原理和在地震监测中的意义出发,以GNSS观测的地震数据为基础,将数据进行解算和分析,对GNSS技术在地壳速度场分析、水平应变速率计算、地壳垂直升降研究以及断层活动分析等在地震监测预报中的应用进行了探讨。结果表明,GNSS在地震监测预报方面具有较好的效果。
In this paper, the experiment of fluxgate magnetometer observation in ordinary cave in Taian station is introduced. Analysis on data of fluxgate in observatory cave and geomagnetic observation room in Taian, respectively, on aspect of correlation coefficient of diurnal variation diurnal variation amplitude, daily mean value, mean value of midnight, and high voltage DC interference, are carry out. The result of comparative analysis shows that, the diurnal range of observation data in ordinary cave is less than that in the geomagnetic observation room, while the daily variation of mean, midnight mean are very well consistent. in the analysis of prediction, can adopt the suitable method, such as vertical component ratio of daily variation, geomagnetic loading-unloading response etc. The observation of fluxgate magnetometer in ordinary cave is feasible, can be used as an accessorial way of geomagnetic observation.
According to the actual situation of Jiaxiang GNSS base station,This article has been given a detailed de-scription of lightning protection measures for base station. Especially lightning protection in mountain area ,what jiaxiang GNSS base station to do is relatively successful,which can be used for reference to other base stations and some similar geological conditions stations ,microwave radar stations,television stations and other stations.
