Currently (July 2014) an uninterrupted information about the ship’s position can be obtained from specialized electronic position-fixing systems, in particular, Satellite Navigation Systems (SNSs) as GSP and GLONASS and Satellite Based Augmentation Systems (SBASs) as EGNOS or WAAS. On each ship’s bridge one GPS stationary receiver is installed at least but on many ships there are two or even more GPS receivers. Nowadays, several hundred different end-user products and broad/chipset/modules are available on the world market, however for ship’s bridge several dozen models provided by a dozen or so manufacturers are designed only. In this paper 309 GPS receivers, 47 different models of 12 manufacturers installed on 188 ships of different types and with different lengths were taken into account. The relations between the type and the length of the ship, the number of the GPS receivers installed on one ship, the manufacturers and the models the most frequently used are presented.
