摘要
Abstract
Baseline of length can be calibrated with three types of instrument. Uncertainty of calibration with invar tape and electro-optical distance measurement instrument were analyzed. Expanded uncertainty (k=2) of the two kinds baseline reached 1 mm in 1 000 m distance. Systemic difference of the three calibration methods about 3 mm/km described by using six times experiment data were measured in Finland, Beijing, Zhengzhou and Chengdu with three EDM instruments. Some solutions were proposed.关键词
