Gyroscope on de Broglie Waves: Intricate Things in Simple Words

The paper addresses the operating principles of a gyroscopic de-vice of a new type: a gyroscope on de Broglie waves. The sensitive element of such a gyroscope is an atomic interferometer, whose main components are described and the technical challenges of its development are discussed. The target audience of this paper is the readers who do not have a profound knowledge of the quantum physics.

Prospects of high sensitivity atomic interferometer development for current gravimetry

A review of the experimental results achieved in the process of atomic fountain clocks construction at “VNIIFTRI” is presented. A possibility of the application of achieved results to the development of a sensitive interferometer (gravimeter) based on cold rubidium atoms is analyzed. The relevance of the study is in the estimation of perspective of interferometer (gravimeter) based on cold atoms for absolute measurements of local free-falling constant development. Physical fundamentals of atomic gravimeter’s operation are described. A comparison between atomic gravimeter and atomic quantum frequency standard based on cold atoms is done. Engineering solutions, that are necessary for building atomic gravimeter with required sensitivity of free-falling acceleration measurement are suggested. In order to build a gravimeter with a sensitivity reaching 1 μGal/Hz1/2 the estimations of laser phase noise, residual gas pressure in vacuum system and magnetic shielding system’s parameters are made.

Promising directions for the development of aircraft orientation and navigation systems

The analysis of physical principles, which can be successfully uses for development a new generation of orientation and navigation systems, as well as errors limiting the prospects for improving these systems, is presented. Monitoring and control of motion in near-Earth space by the gravitational potential, by the geomagnetic field, on the base of the atomic interferometer, by the global pulsar navigation grid and using other methods are considered. New methods based on the results of research in the field of observational astrophysical, laser and atomic interferometry, and the optics of moving media are considered.
