All these systems, called GNSS (Global Satellite Navigation System), are undergoing construction or modernization (new satellites, new frequencies, new signals, new monitoring stations, etc.) and continuous improvement to increase its accuracy, availability, integrity, and resistance to interference. The most significant events in SNS and SBAS in the nearest 10 years are presented also. Additionally three possible scenarios considering these systems (in 2016 and 2021 years), concerning the number of satellites in particular, optimistic, pessimistic and the most probable were taken into account.}, issn = {2083-6473}, publisher = {Gdynia Maritime University, Faculty of Navigation}, keywords = {Global Navigation Satellite System (GNSS), Satellite Based Augmentation System (SBAS), Global Positioning System (GPS), EGNOS, Galileo, Multi-Functional Transport Satellite Based Augmentation System (MSAS), GLONASS, Wide Area Augmentation System (WAAS)} }
