"With four new and emerging constellations (BeiDou, Galileo, QZSS, IRNSS) as well as the ongoing modernization of the U.S. Global Positioning System and Russia\u2019s GLONASS, the world of satellite navigation is undergoing dramatic changes. Facing these challenges, the International GNSS Service has initiated the Multi-GNSS Experiment to enable an early familiarization with the new systems and to prepare their incorporation into high-precision GNSS modeling and analysis. This article reports on the status of the new constellations and the MGEX project and describes initial data products and recent results for individual systems."@en . . . .
