Resumen

This paper describes the evaluation of the accuracy of determinations of a ship’s position by means of Navy Navigation Satellite System (NNSS) receivers. Using a dual channel receiver, type RSN-2, manufactured by the British firm Redifon Telecommunications Ltd., measurements were carried out in the following South American ports : Callao (Peru), Grytviken (South Georgia), Montevideo (Uruguay), Port William (Falkland Islands) ; and for the port of Gdynia (Poland) an American-made single channel receiver, Magnavox type MX-1102, was used. The results were compared with the geodetic positions on navigational charts and also with transformed coordinates in several geodetic systems obtained from the GEOCN (Geodetic Coordinate Conversion) computer program.
