    • MODULE 1GNSS (GPS) Workflow and Integration into GIS Karyn Nolan
    • Top 3 Questions What is the accuracy of the equipment? How do I have a picture as an attribute? Why is my data in the ocean? ….other tips along the way
    • Differential CorrectionsReal Time Accuracy Autonomous – 10 m with uncorrected GPS Satellite Based Augmentation System (SBAS) – 1-5 m – WAAS - US – EGNOS - Europe – MSAS – Japan – GAGAN - India
    • VRS - Difference in Accuracybetween traditional RTK and VRS
    • Future Trend Real Time Accuracy VRS subscription or Single Base broadcast – cell phone or radio – http://www.trimble.com/infrastructure/services.aspx 100cm VBS/WAAS/EGNOS 15cm XP/G2 10cm HP 4cm CenterPoint RTX 2cm RTK/VRS 0cm
    • Trimble VRS Now Network Europe: Czech Republic, Estonia, Great Britain, Germany, Netherlands, Belgium, Luxembourg & Ireland Estonia Ireland Great- Netherlands Britain Germany Belgium Czech U.S.: Alabama, Colorado, Florida, Illinois, Lux Iowa, Indiana, Kentucky, Mississippi and Nebraska Madrid
    • Differential Corrections – Post Process Post Processed Accuracy (PPA)  Corrections applied in office software – CORS – Achieve Specifications of Equipment!!
    • Global Navigation Satellite SystemWhat is the Global Navigation Satellite System, GNSS? GPS – US Global Positioning System GLONASS – Russian GLObal NAvigation Satellite System Galileo – European Union (currently non-functional)
