in the Lower Odra River using DGPS

The increase in the barge-carried cargo volumes in the Lower Odra River area necessitates the tracking of barge traffic in order to ensure the safety of navigation. The Dziwnow DGPS reference station, designed for marine traffic, is located near the mouth of the Odra River. The paper presents the results of investigation into the availability of DGPS signal transmitted by the Dziwnow reference station in the Lower Odra River area between Kostryd and Szczedn.
