GPS corrections from the European Geostationary Navigation Overlay Service can improve the positioning accuracy and user experience of GPS-enabled mobile phones, even if EGNOS satellites are not visible and even when the GNSS chipset in the phone does not support satellite-based augmentation systems.
We now definitively declare “curtain up!” on the second act of the human and technological drama, Interoperable Global Navigation Satellite Systems, by many authors, directors, and actors, upon the global stage. It happened on August 2 with removal of the message 0 (“Do Not Use in aviation”), by the European Satellite Services Provider, from the European Geostationary Navigation Overlay Service (EGNOS) signal.

After reviewing current performance of WAAS, EGNOS, and MSAS, the authors present expected future performance, including the benefits of GPS L5. They evaluate the impact of the Indian GAGAN and Russian SDCM systems on global coverage and examine southward expansions for the original three SBASs. Finally, a look at the impact of a second constellation of navigation satellites and the performance for a user taking advantage of two core constellations.
