Brief overview of GNSS –Overview of GPS –Ranges –Timing –Timing Errors –Geometry –Atmospheric Conditions –RTK –Satellite constellations
Overview of GPS Global Positioning System (GPS) Trimble Tutorial on GPS (http://www.trimble.com/gps/howgps.shtml) Trimble Tutorial on GPS A minimum of 4 satellites are required to provide a unique solution
Ranges We do know the Velocity of the Satellites signals To get the time travelled we need to synchronize the clock in our receiver on the ground with the clocks in the Satellites. Thus satellite positioning is based on clocks!
Timing To get perfect synchronisation we can use an additional satellite signal. Thus we need a minimum of five satellites for the initial position solution.
Timing Errors Despite having perfect synchronisation there are still some errors that affect the accuracy.
Geometry Poor Geometry Good Geometry
Atmospheric Conditions Relatively close locations have similar atmospheric conditions
RTK Corrections for the Satellite are sent to the GNSS Receivers
Satellite constellations GPS - US system Glonass- Russian system Galileo- European Union system Compass- Chinese system QZSS- Japanese system
