1 Training and Presentation Field Training

2 Contents  Brief overview of GNSS  Overview of the Terralite constellation  Terralite constellation Hardware  Firmware Versions  Software Overview  Trouble shooting

3 Brief overview of GNSS –Overview of GPS –Ranges –Timing –Timing Errors –Geometry –Atmospheric Conditions –RTK –Satellite constellations

4 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

5 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!

6 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.

7 Timing Errors  Despite having perfect synchronisation there are still some errors that affect the accuracy.

8 Geometry Poor Geometry Good Geometry

9 Atmospheric Conditions  Relatively close locations have similar atmospheric conditions

10 RTK  Corrections for the Satellite are sent to the GNSS Receivers
