摘要/Abstract

摘要： 针对陆态网络GNSS连续站分区设计了三种方案,其中方案1(区域方案)将测站按区域划分为6个子网,每个子网包含55个测站;方案2(大网方案)分为3个测站全国分布的子网,每个子网包含100 个测站;方案3(小网方案)分为8个测站全国分布的子网,每个子网包含55个测站。按照上述三种方案分别处理了陆态网络2010年第110天至2013年第103天的观测数据,从测站时间序列、点位水平速度场、两点间基线长度三个方面对比分析了三种方案解算结果之间的差异。结果表明,不同的方案解算结果存在差异但差异量值较小。综合.上述分析结果和计算耗时等因素,讨论了陆态网络GNSS连续站分区方案的选取。

Abstract: Aiming at sub-network division of GNSS continuous stations in TEONET (Tectonic and Environmental Observation Network in China), we design three schemes to process the data from doy 110 in 2010 todoy 103 in 2013. The first scheme (referred as regional scheme) has six regional sub networks and each sub network includes 55 GNSS permanent stations. The second scheme ( named large- net scheme) has three sub- networks and each has 100 stations selected evenly in mainland China. The third scheme (named small- net scheme) has eight sub networks and each has 55 stations selected evenly. Meanwhile, we analyze the differences between the results including sta tion coordinates, horizontal velocity field and baseline length. The results show that the differences are within the current observation and calculation precision. From the above motioned results and considering other factors such as computing time, we discuss the selection of sub- network division schemes in TEONET.

Key words: Sub-net work division scheme, Difference analysis, TEONET, GNSS continuous stations
