  2. NGS - RT Program Components Develop and Publish Guidelines Describing Best Practices. Provide Outreach and Education Research Scientific Research Affecting Accurate Real-Time Positioning. [satellite orbits, refraction, multipath, antenna calibration, and crustal motion.] NGS Streams Raw Data From The Backbone CORS

  4. Summary Table RT Single-Base Guidelines

  5. NGS GuidelinesReal Time GNSS Networks • Site Considerations • Planning and Design • Administration • Obtaining Station Coordinates Consistent with NAD83 and ITRS • User Best Methods

  6. Obtaining Station Coordinates Consistent with NAD83 and ITRS • Include a subnetwork of the RTN into the National CORS network. This would be three stations If RTN has less than 30 stations, 10% of RTN with greater than 30 stations. NGS will not distribute/broadcast RTN reference station data. • Align all RTN reference stations coordinates to the CORS network at 2-cm horizontal and 4-cm vertical • For each reference station in the RTN, use the Online Positioning User Service (OPUS) at http://www.ngs.noaa.gov/OPUS/ to test for the continued consistency of its adopted positional coordinates and velocity on a daily basis, and revise the station’s adopted coordinates and/or velocity if the tests reveal a need to do so.

  7. Best methods from the Guidelines:The 7 “C’S” of NOAA’s NGS The Control is at the Pole • Check Equipment • Communication • Conditions • Calibration (or not) • Coordinates • Collection • Confidence

  8. CO Spatial Reference Network • CSRN Board meetings • Thursday, April 18th, 2013, 5:30 to 7:00 pm.  Location to be determined • Thursday, September 19th, 2013, 5:30 to 7:00 pm.  LTBD • CSRN Membership meeting • Thursday, November 21st, 2013, 5:30 to 7:00 pm.  LTBD, topic and speaker to be selected • Events • Saturday, August 17th, 2013 – GPS Day.  LTBD • Sometime in August or September – CSRN and Northern PLSC Chapters Picnic – Theme, checking instrument calibration

  9. CBLs • June 13 and June 19 • Workshop (How to) • Re-Measure Highline • Re-Measure Durango • New CBL in Denver Metro Area • Complete all other CBLs in 2014

  10. Ohio CBL http://digital.bnpmedia.com/publication/?i=143556&p=25 Feb 2013 POB

  11. CBLs

  12. A Question to Consider: What is good enough with respect to the NSRS, i.e. have we reached a level of precision and accuracy where further realizations (adjustments) are unnecessary?

  13. Next Steps/Priorities • CBL • OPUS-DB (Begin implementing) • Heights -Study

  14. What Can You Do? • Collect Metadata • Know what accuracies you need • Utilize the tools that are available • Work on the latest datums and realizations • Contact your local advisor if you are having issues • Utilize the many webinars

  15. NGS Training Center Webinars! http://www.ngs.noaa.gov/corbin/
