“…bias drift ranging from 0.001 • /h to 1 • /h and resolution from 0.01 • /h to 10 • /h. These sensors have been utilized in several space missions such as Pleiades for the Earth observation [12], Aeolus for the observation of the atmospheric wind profile [13], and Planck to study the cosmic background radiation [14]. Due to the sensitivity to external perturbations (vibration transients, thermal and stress perturbations), FOGs cannot be extensively used for aircraft inertial navigation, due to a very harsh environment, while they are suitable for selected space applications where vibration and temperature transients are not so severe, even though attention will be paid to the ionizing radiation sensitivity.…”

Low-cost chip-scale optoelectronic gyroscopes having a resolution ≤ 10 • /h and a good reliability also in harsh environments could have a strong impact on the medium/high performance gyro market, which is currently dominated by well-established bulk optical angular velocity sensors. The R&D activity aiming at the demonstration of those miniaturized sensors is crucial for aerospace/defense industry, and thus it is attracting an increasing research effort and notably funds.In this paper the recent technological advances on the compact optoelectronic gyroscopes with low weight and high energy saving are reviewed. Attention is paid to both the so-called gyroscope-on-a-chip, which is a novel sensor, at the infantile stage, whose optical components are monolithically integrated on a single indium phosphide chip, and to a new ultra-high Q ring resonator for gyro applications with a configuration including a 1D photonic crystal in the resonant path. The emerging field of the gyros based on passive ring cavities, which have already shown performance comparable with that of optical fiber gyros, is also discussed.
