Global Navigation Satellite Systems (GNSSs) provide the services on positioning, time, and navigation aspects of ground, marine, and aviation to our society. The integration of GNSS, telecommunication, geographic information systems, and remote sensing technologies have demonstrated their utility in the remote sensing of earth’s atmosphere and ionosphere. In this chapter, the basics of the Global Positioning System (GPS), its components and different transmitted GPS signals are described. The different error sources introduced in GPS/GNSS measurements are described with the main emphasis on the tropospheric error sources. GNSS meteorology is now an established atmospheric remote technique that can provide the data on integrated water vapor (IWV) which is the most abundant and important greenhouse gas for meteorological and climatic processes. The IWV is one of the key parameters to understand atmospheric structure and processes, including severe terrestrial weather phenomena and climate change.
