To date, a ship’s position can generally be obtained from functional satellite navigation systems (SNS), such as Global Position Systems (GPS and GLONASS), and Satellite-Based Augmentation Systems (SBAS), such as (European Geostationary Navigation Overlay Service (EGNOS), GPS-Aided Geo Augmented Navigation system (GAGAN), MTSAT Satellite Augmentation System (MSAS) and Wide Area Augmentation System (WAAS). Sometimes these systems are collectively called Global Navigation Satellite Systems (GNSS). Two more SNS, Galileo and BeiDou, one more SBAS, System for Differential Corrections and Monitoring (SDCM), and new regional systems, such as Quasi-Zenith Satellite System (QZSS) in Japan and Indian Regional Navigation Satellite System (IRNSS) in India, are also under construction. Information about all of these 11 systems is available on the internet. The number of links and the type of the information obtained from two search engines, Google and Bing, for the different keywords concerning each system are shown in the paper. Additionally, the analysis of the character and usefulness of the information placed on the pages of governmental organizations and institutions administering the above-mentioned systems, manufacturers of the satellites, receivers and different kinds of the institutional users is also provided.
