摘要

A low size, weight, power, and cost (SWaP-C) single-axis Interferometric Fiber Optic Gyroscope (IFOG) has been developed at LEOS for space applications. Navigation-grade performance (Angle Random Walk (ARW) \(\le \) 0.0005 deg/ \(\sqrt{hr}\) and bias stability \(\le \) 0.003 deg/hr) has been demonstrated by using COTS optical and electronic components in a closed-loop configuration, achieving a mass of 750 g and 6 W of power consumption. This paper briefly presents the optical, electronic, and mechanical aspects of the development along with preliminary test results.
