A Look at the Development of GNSS Capabilities Over the Next 10 Years

This paper considers what the SNS (Satellite Navigation Systems) as GPS, GLONASS, Galileo and Compass, and SBAS (Satellite Based Navigation Systems) as EGNOS, WAAS, MSAS and GAGAN ser-vices might look like 10 years from now. All these systems, called GNSS (Global Satellite Navigation System), are undergoing construction or modernization (new satellites, new frequencies, new signals, new moni-toring 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.
