In modern geodesy high demands are placed on the accuracy of linear measurement. The measurement methodology and surveying instruments used have to be adjusted to meet these stringent requirements, especially the electronic distance meters as the most often used instruments. We have considered the problems of metrological provision of laser range finders. The possibility of creation of laboratory reference linear basis of the compact sizes with control lines of the increased length at preservation of high precision of measurements described. Such result achieved by combining of schemes of fiber-optical and interferential linear bases. The function chart of fiber-optical and interferential linear bases for control of accuracy of total stations showed.
