Satellite clocks characterization and monitoring for global navigation satellite systems
2011 XXXth URSI General Assembly and Scientific Symposium, 2011In Global Navigation Satellite Systems (GNSS) the user's position is determined measuring the time of flight of the signals broadcast from satellites, which is proportional to the distance between the user and each satellite of the constellation. Time and frequency metrology has an essential role in satellite navigation systems: since a distance can be

Global Navigation Satellite Systems
2014The last few years there has been increased interest in the commercialization of the Global Navigation Satellite System (GNSS) which is often referred to as the Global Positioning System (GPS) in various applications. A GPS system uses spread spectrum signals-binary phaseshift keying (BPSK)-emitted from satellites in space for position and time ...

Global Navigation Satellite Systems
2015Our modern world is interconnected with advanced technologies. All aspects of our lives are dependent on our ability to measure space and time every day. “Where are we and what time is it”? These two basic questions connect us to all aspects of our modern, technologically driven lives. Satellites, in this case, Global Navigation Satellite Systems (GNSS)

Global Navigation Satellite Systems and Inertial Navigation
2011When one would rank the geo-data collection techniques developed the last three decades or so from most significant to least significant, positioning and navigation by means of Global Navigation Satellite Systems (GNSS) would head the list. GNSS enables obtaining precise positioning and timing information anywhere on land, on sea or in the air, day or ...
