摘　　要：以GAMIT/GLOBK新版本10.71中新增的北斗三号数据处理和辐射压力模型等内容为对象,首先介绍了GAMIT/GLOBK软件版本的发展,然后阐述了10.71版本的数据解算流程,最后利用软件对6个MGEX跟踪站2021年256年积日的GNSS数据进行处理,通过标准化均方根误差NRMS、解算总结指标、内符合精度、外符合精度4个方面对GPS、BDS和联合解算结果进行对比分析。结果表明:采用10.71版本解算GPS、BDS和联合解算结果可靠,精度厘米级,综合评估联合解算优于GPS、BDS,GPS与BDS精度相当。The new version of GAMIT/GLOBK is 10.71,with the addition of Beidou-3 data processing and radiation pressure model.This paper first introduces the development of GAMIT/GLOBK software version,then describes the process of data solution for version 10.71,and finally processes the GNSS data of six MGEX tracking stations for the 256 days of the year 2021 by the software,the results of GPS,BDS and joint calculation are compared and analyzed from four aspects:normalized root mean square error NRMS,calculation summary Index,inner coincidence accuracy and outer coincidence accuracy.The results show that the solution of GPS,BDS and the joint solution using version 10.71 is reliable and the accuracy is at centimeter level.The integrated evaluation of the joint solution is superior to GPS and BDS and the accuracy of GPS and BDS is equivalent.
