1. An apparatus acting as an optical gyrocompass with a portable form factor, the apparatus comprising:
a rigid frame forming part of a housing of the apparatus; and
a fiber optical gyroscope having a fiber coil wrapped around the rigid frame, wherein the fiber coil is used as a rotation sensing element of the fiber optical gyroscope that provides high-precision inertial navigation data along a critical axis, and wherein the fiber optical gyroscope further comprises an integrated photonics front-end-chip coupled to the fiber coil.
