Abstract
The article discusses communication facilities for transmitting corrections and ephemeris data, analyzes methods of calculating errors of satellite position finding, and gives results of field tests for determining accuracy of the location for Real Time Kinematic and Precise Point Positioning modes. There has been carried out a survey of the existing functioning differential satellite subsystems, satellite differential correction and monitoring systems. The methods of differential coordinate correction currently used on the inland water transport provide accuracy within 1-5 meters. As in the unmanned mode the given accuracy is not sufficient, there appears the need to develop methods for calculating location finding with centimeter precision. Precise positioning relative to the axis of the ship's course will make it possible to control the vessel in the unmanned mode, as well as to use robotic facilities on water transport capable of making safe voyages on a set of waypoints tied to geographical coordinates.
