№ 1 (29) 2022

The first issue of this year’s “Almanac” No. 1 (29) begins with a foreword by the editor-in-chief.
Of undoubted interest should be a fundamental review of the team of authors on the state of development of mobile time and frequency standards for solving the problem of quantum leveling.
Important questions are raised in the articles of the traditional sections of the Almanac, such as “Coordinate-temporal measurements”, “Gravitational measurements”, “Hydroacoustic measure­ments”, “Acousto-optic measuring instruments”.
The issue informs the reader about new books on metrology published by the FSUE “VNIIFTRI” publishing house.
Traditionally, there is a heading “The founders of metrological directions”.
