  • 摘要:This paper introduces in detail methods about calibration length baseline based on μ-base distance meter, and errors in the calculation of oblique distance model; the measurement of meteorological parameters and the correction of height difference are analyzed quantitatively by means of equation derivation. Through the calibration results of μ-base and invar tape, systematic differences between the two measurement methods were found out at the Yellow River Embankment Length Baseline in Zhengzhou. Based on a TS30 total station instrument with stable performance, according to the calculation results of "analytical method" and "comparative method", the accuracy of the two calibration results between μ-base and invar tape is compared and evaluated. In the end, some suggestions to improve the accuracy of using μ-base to calibrate length baseline are given.
