摘　　要：针对工程测量中高精度数据处理的需要,天宝公司研发的新版本TBC 4.0软件不仅兼容多导航定位系统,而且显著改进了长基线解算精度。本文基于IGS观测数据,将TBC 4.0软件的基线解算精度与Bernese软件、GAMIT软件基线解算精度进行了对比,并与旧版本TBC软件解算能力进行了比较。结果表明,在1000 km长基线的情况下,TBC 4.0软件获得了与Bernese、GAMIT软件相当的解算精度,三维位置精度为毫米级,且不受星历类型的限制。另外,与旧版本TBC相比,TBC 4.0软件的基线解算能力有了很大的提高。In response to the demand for high-precision data processing in engineering surveying,the new version TBC 4. 0 software developed by the Trimble company is not only compatible with multi-navigation positioning system,but also significantly improves the accuracy of long baseline solution.In this paper,based on the observation data of IGS,the baseline solution accuracy of TBC 4.0 software is compared with that of Bernese software and GAMIT software,and compared with the solving ability of TBC software for old version.The results show that in the presence of a long baseline of 1000 km,the resolution accuracy of TBC 4.0 software is comparable to that of Bernese and GAMIT software,with a three-dimensional position accuracy of mm level. What＇s more,it is not limited by the type of ephemeris.In addition,the ability of baseline solution for TBC 4.0 software has been greatly improved compared with the old version of TBC.
