摘要
IGS在1992.6.21～1992.9.22组织了全球GPS联测，在此期间的7.26～8.8二周时间为加强观测，参加台站多达600余个，用以研究GPS的各个方面，取名为EPOCH′92。本文对EPOCH′92期间前后共18天的全球分布的24个站的资料进行了归算处理，得到的基线精度为5mm+8.35ppb，定轨精度好于2m，地球定向参数x_p，y_p解的精度约为1mas。
:International GPS Geodynamic Service(IGS)had organized a global GPS ca-mpaign during June. 21. 1992-Sept. 22. 1992, in which July. 26-Aug. 8 for the re-inforced observational period, named EPOCH'92.Over 600 stations took partin the campaign.The campaign is aimed to study precise orbit determination ofGPS satellites and GPS applications in Geodesy and Geodynamic.In this paper,the data of total 18 days around EPOCH'92 from 24 global distributed sta-tions has been processed .The measuring accuracy of the global baselines is 5mm +8.35ppb.The accuracy of orbit determination is better than 2m.The determiningaccuracy of polar motions (xp,yp) is about 1 mas.
