Discussion of trigonometric leveling by TM30 measurement robot replacing the second order leveling

In order to overcome the problems of low efficiency and labor intensive with the second leveling survey,this study uses trigonometric leveling survey by high precision total station TM30 survey robot to replace the second leveling survey.According to trigonometric leveling principle,using the data obtained by Leica TM30 total station’s trigonometric leveling survey,and using the data from Zeiss NI005A precise level’s second order leveling survey,their measurement accuracy are analyzed.In addition,the optimal selection of atmospheric refraction coefficient K is discussed.The results show that high-precision trigonometric leveling survey using TM30 total station can replace the second order leveling survey under certain conditions,and the study results have greatly improved the work efficiency of the second leveling survey.
