We analyse the possibilities for realizing a wide area differential navigation based on the GNSS-1 signals, as applied to comparatively small regions on the Earths surface such as Ukraine. The accuracy of the differential corrections formed by the reference station network and the resulting accuracy are estimated at 1.3-2.1 m for the coordinates and 0.7-1.2 cm/s for the velocity, which corresponds to the GNSS-1 requirements.
