Abstract This article provides a brief overview of the state-of-the-art development of a new generation of gyros on cold atoms for space applications. The problem of narrowing the dynamic range of atomic interferometers in comparison with optical interferometers and method for resolving this problem are discussed. Three new results are presented for the first time in the world: 1) A new “kinematic” gyroscopic principle that allows one to determine uniquely the absolute angular velocity without limitations on the measurement range, in contrast to the interferometric gyroscopic principle; 2) Accurate expressions of gyroscopic effects on cold atoms and on de Broglie waves based on kinematic and interferometric gyroscopic principles, which are fundamentally different from the Sagnac effect; 3) The asymmetry of the particle-wave duality seen in gyroscopy: an increase in the sensitivity to rotation when stepping from photons to cold atoms is colossally greater than the increase in sensitivity when stepping from light waves to de Broglie waves of the order of (1013 ÷ 107) at atom temperature of the order of (10−9 ÷ 10−3) K.
Highlights For the first time proposed new "kinematic" gyroscopic principle. Accurate expressions of gyroscopic effects on cold atoms and on de Broglie waves. The absence of the Sagnac effect on cold atoms and on de Broglie waves. Colossal asymmetry of the particle-wave duality in gyroscopy.
