Precise positioning with current multi-constellation Global Navigation Satellite Systems: GPS, GLONASS, Galileo and BeiDou
The world of satellite navigation is undergoing dramatic changes with the rapid development of multi-constellation Global Navigation Satellite Systems (GNSSs). At the moment more than 70 satellites are already in view, and about 120 satellites will be available once all four systems (BeiDou + Galileo + GLONASS + GPS) are fully deployed in the next few years. This will bring great opportunities ...
متن کاملPerformance of GPS, GLONASS and Galileo
After a short introduction, an overview about the Global Navigation Satellite Systems (GNSS) GPS, GLONASS and Galileo is given. For each system, a status report is presented and then the three main positioning algorithms: Single Point Positioning, Differential Pseudorange and Carrier Phase Positioning are described. In the Summary, the systems are compared and and outlook is given.
متن کاملGlobal navigation satellite systems
Global positioning systems first became available for private use in 1995. Since the introduction of NAVSTAR-GPS (Navigation System with Time and Ranging–Global Positioning System) and GLONASS (Globaluaya Navigatsionnaya Sputnikovaya Sistema, Global Navigation Satellite System), such systems have quickly become indispensable in a wide range of applications. Above all, GPS is used today by a lar...
متن کاملGlobal Ionospheric Modelling using Multi-GNSS: BeiDou, Galileo, GLONASS and GPS
The emergence of China's Beidou, Europe's Galileo and Russia's GLONASS satellites has multiplied the number of ionospheric piercing points (IPP) offered by GPS alone. This provides great opportunities for deriving precise global ionospheric maps (GIMs) with high resolution to improve positioning accuracy and ionospheric monitoring capabilities. In this paper, the GIM is developed based on multi...
متن کاملImplications of a “system of Systems” Receiver
The US Global Positioning System (GPS) and the USSR (and later Russian) system Glonass have existed for decades. Europe is developing Galileo and China launched Beidou which was the first Regional Navigation Satellite System (RNSS) and then announced Compass, a Global Navigation Satellite System (GNSS). Japan is planning its own regional augmentation to GPS and Galileo known as the Quasi-Zenith...
