Topology-adapting routing strategy for global navigation satellite system
International Journal of Distributed Sensor Networks, 2017 In order to implement global precision navigation, the global navigation satellite system must rely on information exchange with the ground station to achieve system time synchronization and inter-satellite ranging. For the limitations of ground stations

Global navigation satellite system [PDF]
, 2017 The last few years have shown an 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 phase-shift keying (BPSK)-emitted from satellites in space for position and time ...
