  1. Global Navigation Satellite System G N S S WEB-simulation Global Navigation Satellite System

  2. Global Navigation Satellite System Schedule Philip Wenting • Short explanation • Equipment, old and new • Demonstration outside ? Questions? Please interrupt and ask! Global Navigation Satellite System

  3. Global Navigation Satellite System Terminology is changing !No longer GPS but GNSS Global Navigation Satellite System

  4. Global Navigation Satellite System • Now active • GPS USAGlobal Positioning System • GLONASS RussiaGLObal'nayaNAvigatsionnayaSputnikovayaSistema Global Navigation Satellite System

  5. Global Navigation Satellite System • Future • Compass ( Beidou-2 ) China (Ursa Maior) • Galileo Europe Global Navigation Satellite System

  6. Global Navigation Satellite System • Regional • IRNSS IndiaIndian Regional Navigational Satellite System • Beidou-1 China • Doris FranceDoppler Orbitography and Radiopositioning Integrated by Satellite • QZSS JapanQuasi-Zenith Satellite System Global Navigation Satellite System

  7. Global Navigation Satellite System Technical information A satellite is a radio transmitter Distance to earth: 20200 km. Frequency and Wave length ( ± 20 cm.) With 28 satellites always 4 “visible”, and why 4? Global Navigation Satellite System

  8. Global Navigation Satellite System • Positions directly calculated from Satellite data are always wrong ! • Why ? Global Navigation Satellite System

  9. Global Navigation Satellite System • Accuracy • Standard up to 10 metres • Differential up to 1 metre • RTK few cm And almost everything in between, depending on the budget ! More money >> higher accuracy. Global Navigation Satellite System

  10. Global Navigation Satellite System • Better results • Averaging • Correction from a geostationary satelliteWAAS (Wide Area Augmentation System) EGNOS (European Geostationary Navigation Overlay Service) • Radio beacon (Long distance) • Base station (Short distance)Real position on a known point Virtual ( 06-GPS-Netwerk ) Global Navigation Satellite System

  11. Global Navigation Satellite System • Where to find more information? • Everywhere on the WWW, search for GNSS on • Googleor • Wikipedia Global Navigation Satellite System

  12. Global Navigation Satellite System When GNSS is not possible:use other landsurveying techniques and/or equipment ! Global Navigation Satellite System

  13. Global Navigation Satellite System Routes outside Forum Made with Garmin’s On 2 october 2013 Click Global Navigation Satellite System

  14. Global Navigation Satellite System Thank you for your attention.Please remind :No longer GPS but GNSS ! Global Navigation Satellite System
