摘要

A brief overview of state-of-the-art in developments of new gyros based on: 1) the de Broglie waves of atoms and Bose-Einstein condensates; 2) the properties of superfluid's phase quantization is presented. Sensitivity to the absolute rotation of these types of gyros exceeds the sensitivity of laser gyros (LG) and fiber-optic gyros (FOG) based on Sagnac effect of light waves by nine-eleven orders (10~9 -10~(11)) or by a factor of mc~2/hv which is the ratio of atom energy to photon energy. This difference, potentially, allows exceeding significantly the accuracy level that is available for LG and FOG. The devices based on the Sagnac effect of matter-waves were demonstrated and used to detect the Earth's rotation about 30 years ago. Since that time, the accuracy of laboratory samples of such type gyroscopic devices was increased by five orders of magnitude: bias stability is better than 0.0001 deg/h, angle random walk is less than 5 ×10~(-6) deg/h~(1/2) , and the scale factor stability is better than 5 ppm (1σ). Technical solutions of the above-mentioned gyro-devices of the world leading research centers are discussed. A brief comparison with LG and FOG technologies is presented.
