摘　　要：以一新建超短基线场中的GPS站点为研究对象,利用周边IGS站及CMONMC站点作为参考站,使用TBC 4.10与GAMIT 10.7软件进行联合解算,以多种评价指标进行基线解算与坐标解算性能评价。结果表明,在基线解算结果方面,两种软件基线解算结果在水平及长度分量上的基线重复率均满足亚毫米级,而在垂直分量上的基线重复率部分为亚毫米级,部分为毫米级,两种软件基线解算结果与真值偏差均小于3 mm,符合精度要求;在坐标解算结果方面,无论是水平分量还是垂直分量,GAMIT 10.7软件解算坐标与坐标真值偏差均小于2 mm,TBC 4.10软件解算坐标与坐标真值偏差最大可达3.7 mm。相较于TBC 4.10软件,GAMIT 10.7软件在数据处理过程中具有更高的解算精度与可靠性。This paper takes a GPS station in a newly built ultra short baseline field as the research object,uses the surrounding IGS stations and CMONMC stations as reference stations,uses TBC4.10 and GAMIT10.7 software for joint solution,and uses a variety of evaluation indicators to evaluate the performance of baseline solution and coordinate solution.The results show that in terms of baseline solution results,the baseline repeatability of the baseline solution results of the two softwares in the horizontal and length components reach the submillimeter level,while the baseline repeatability of the vertical components is partially submillimeter level and partially millimeter level,and the deviation between the baseline solution results of the two softwares and the true value is less than 3 mm,meeting the accuracy requirements;in terms of coordinate solution results,the deviation between the coordinates calculated by GAMIT10.7 software and the true value of coordinates is less than 2 mm for both horizontal and vertical components,and the maximum deviation between the coordinates calculated by TBC4.10 software and the true value of coordinates can reach 3.7 mm.Compared with TBC4.10 software,GAMIT10.7 software has higher accuracy and reliability in data processing.
