Presentation Transcript

  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) • 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

  11. Satellite constellations • GPS - US system • Glonass - Russian system • Galileo - European Union system • Compass - Chinese system • QZSS - Japanese system
