We propose and implement the scheme of a whole-fiber double-polarization ring interferometer based on an isotropic fiber for gyroscopy purposes. The results of an experimental study of the output signal of the interferometer based on the proposed scheme are presented. The shift of the zero point of the interferometer signal (at a level of 3°/h) and the drift of the zero point (at a level of 1°/h) are determined. The rotation sensitivity of the interferometer is measured. It amounts to 0.1°/h, which agrees well with the calculation allowing for the shot noise of the photoelectric current at the output of the scheme.
