Comparison and Application of TBC 4.10 and GAMIT 10.7 in GPS Data Processing
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 maxi-mum deviation between the coordinates calculated by TBC4.10 software and the true value of coordinates can reach 3.7 mm. Com-pared with TBC4.10 software,GAMIT10.7 software has higher accuracy and reliability in data processing.
