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

This paper considers what the SNS (Satellite Navigation Systems), such as Global Positioning System (GPS), GLONASS, Galileo, and Compass; and SBAS (Satellite Based Navigation Systems) such as European Geostationary Navigation Overlay System (EGNOS), Wide Area Augmentation System (WAAS), Multi-functional Transport Satellite Based Augmentation System (MSAS) and GPS and Geo Augmented Navigation (GAGAN) services, 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 monitoring stations, etc.) and continuous improvement to increase accuracy, availability, integrity, and resistance to interference. The most significant events in SNS and SBAS over the last 10 years are presented. In addition, three possible scenarios for SNS in the years 2016 and 2021 (most probable, optimistic, and pessimistic), including the number of satellites, are presented.
