Example Solution of GAMIT/GLOBK 10.71 in GNSS Data Processing
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 re-sults of GPS,BDS and joint calculation are compared and analyzed from four aspects:normalized root mean square error NRMS,cal-culation 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 solu-tion is superior to GPS and BDS and the accuracy of GPS and BDS is equivalent.
