The mature satellite-based navigation systems that are now available (e.g., GPS) have provided adequate positioning capability to users. However, their very success has been a driving force to increase accuracy, availability, reliability, and integrity requirements. As a result, several satellite augmentation systems have been or are in the process of being designed, developed, and/or tested in order to meet the ever-demanding requirements. This paper will provide a summary of the current possibilities to improve GPS performance, namely the impact of the GPS modernization program itself, augmentation with the satellite-based GLONASS, WAAS, MSAS, and EGNOS systems, and augmentation with on-board aiding; e.g., barometers and clocks. Performances are discussed as a function of user mask angle. The impact of combined GPS/GALILEO is briefly addressed.
