№ 2 (26) 2021

The running issue of the “Almanac of Modern Metrology” 2 (26) is the second issue this year. The foreword of this issue raises topical issues of technological breakthroughs in measurement accuracy.
Articles placed in the sections devoted to radio engineering, navigation-gravimetric, hydro­acoustic measurements, highlight the issues of creating complexes of equipment for precise measu­rements. The question is also raised about the software and hardware of the measurement data.
A separate section discusses general issues of metrology, in particular measurement techniques traceable to measurement scales.
Traditionally, there is a heading “The founders of metrological directions”.
