Reason

Future technology information technology would stand for all of continuously evolving and converging information technologies, including digital convergence, multimedia convergence, intelligent applications, embedded systems, mobile and wireless communications, bio-inspired computing, grid and cloud computing, semantic web, user experience and HCI, security and trust computing and so on, for satisfying our ever-changing needs. These developments in GNSS can be of great benefit to the remote sensing community since they will not only allow far higher coverage than can currently be achieved with GPS alone, but also improved signal quality and hence enhancing the quality remotely of the remotely the technology for future instruments.

For both, the increase in numbers of navigation systems (GPS, Galileo, Glonass, Beidou), numbers of satellites, numbers of different frequencies (including possible extension into other bands such as C-band), increase of power transmitted and increase of bandwidth, will all add to the capabilities required of future GNSS instruments.…
