陆态网络GNSS连续站分区解算方案的对比分析

Abstract

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
