福建地壳形变GPS观测台网选址及噪声分析

Reconnaissance And Noise Analysis For GPS Observation Network of Fujian Crustal Deformation

利用福建地壳形变GPS基准台选台过程中 ,在 4个站址上得到的 2 4h连续观测数据 ,计算并分析了各站址背景噪声信噪比 ,认为福州、南平、泉州、龙岩所选点址适宜建站 ,并提出背景噪声信噪比计算结果可用于评价仪器性能和站址安静程度 ,反映台网的监控能力 。

Using continuous observation data of background noises for 24 hours in 4 sites, during the reconnaissance for GPS base stations of Fujian crustal deformation, we calculated and analyzed the signal noise ratios in these sites. Then, we consider that GPS base stations are suitable to be built in Fuzhou, Nanpin, Qiuanzhou and Longyan. It is put forwarded that the results can be used for estimating the capability the instruments, the quite extent of stations and the monitoring capacity of the network. And it provides the references to construct the network.
