It is suggested that the following two fundamental problems should be solved in order to achieve practical implementation of the new definition of the unit of length: fixation of a plane electromagnetic wave at pecified points in space (from the frequencies of a frequency standard) and precision measurement of time intervals in the course of which an electromagnetic wave travels between these two points in space. A method and system based on an optical meander generator and precision frequency-phase comparator are proposed.
