Realization on the Calibration technology of Additive Constant and Multiplication Constant of Total Station Instrument based on the baseline comparison method
This article discussed the calibration technology of total station base on the baseline comparison method that adjustment function model was established taking advanced of difference between baseline standard values and average values of corrected observations of the 21 baselines though which additive constant and multiplication constant of tested Total Station was soluted out.Then statistic t_K and t_R of additive constant and multiplication constant of tested Total Station was constructed using principle of mathematical statistics and by the result of which compared with t_(α/2) values at the cindition of significant difference( α = 0.05 ) and degrees of freedom(r = 19),whether additive constant and multiplication constant of the tested total station is significant was decided.then calculation model of additive constant and multiplication constant was selected. Experimental results show the calibration technology of total station base on the baseline comparison method Is a reasonable and Appliable approach.
