> Abstract: During the next decade enhancements and additions to the network of Global Navigation Satellite Systems (GNSS) will significantly improve the use of space-based positioning systems for surveying, mapping, charting, navigation and numerous other applications.  In order to meet the anticipated demands for an improved geospatial framework that these developments will require, the National Geodetic Survey (NGS) is implementing a plan for the modernization of the National Spatial Reference System (NSRS).  Among the issues outlined in this plan is the adoption of an entirely new geodetic reference frame by 2022, with updated geometric (horizontal) and gravimetric (vertical) realizations that will replace the North American Datum of 1983 (NAD 83) and the North American Vertical Datum of 1988 (NAVD 88).   This new framework will be designed to be virtually identical to and aligned with the International Terrestrial Reference Frame (ITRF), with orthometric heights based exclusively on gravity observations and a high accuracy geoid model.   This presentation will highlight the rational for these changes; the various elements that currently define the NSRS.

> About the Speaker:  Dave Doyle joined the National Geodetic Survey in 1972, and held the position of chief geodetic surveyor upon his retirement in January, 2013.  During his time at NGS his experiences included all phases of geodetic triangulation, astronomic positioning, leveling, GPS data collection, data analysis, datum transformations, network adjustments, and data publication.  Mr. Doyle’s activities have included extensive efforts on the development and implementation of the North American Datum of 1983 and the North American Vertical Datum of 1988.  He has also provided technical support to various countries for the modernization of national and regional geodetic reference systems in Caribbean and Central America, Africa, and the Pacific.
