Document Summary
Gnss (global navigation satellite systems); a system that uses satellites to provide geospatial positioning with global coverage. Gnss satellite systems consists of three major components of segments. Master control stations adjust the satellites" orbit parameters and on-board high- precision clocks when necessary to maintain accuracy. Monitor stations monitor the satellites" signal and status, and relay this information to the master control station. Uploading stations: uploads any change in satellite status back to the satellites. User segment: consists of gnss antennas and receivers used to determine information such as position, velocity, and time. Multiple gnss have been developed by different countries: The global positioning system developed by the us. Most widely used global positioning and navigation system. Worldwide navigation system formed from 24 satellites and their ground stations. Uses satellites in space as reference points for determining locations on earth. The positions of the satellites are known.
