Mr. Henning is employed by the National Geodetic Survey (NGS) as a real-time specialist, helping to develop NGS guidelines and policy related to real-time positioning. He is a registered professional land surveyor in Maryland with over 40 years of active experience in all phases of surveying technology. He has helped plan, implement and manage height modernization geodetic networks for county-wide projects in Maryland and Virginia. Mr. Henning is a Past President of the American Association for Geodetic Surveying (AAGS) and is the NGS representative to the RTCM special committee involved with differential positioning (SC-104). He has presented numerous talks at local, regional and national venues for over 12 years.

Content Summary:

Current estimates show that over 50 Real-Time Networks (RTN) are in operation in the continental U.S., providing a significant benefit-to-cost ratio in positioning technology for the public, private and academic sectors. As the caretaker of the National Spatial Reference System, NOAA's National Geodetic Survey (NGS) is developing guidelines for new applications of positioning using real time techniques.

The goal is to link the burgeoning number of real-time networks (RTN) at a specific level of accuracy aligned to the NSRS.

The guidelines may encompass the design, construction, administration and use of these RTN to insure their integrity and to provide users with the best methods of positioning with real time techniques.

Additionally, the NGS is planning to implement the streaming of real time data in industry standard Radio Technical Commission for Maritime Service (RTCM) format from selected federally owned or operated Continually Operating Reference Stations (CORS), so that RTN administrators may use the data as a fiducial value adjusted into their networks. This presentation will describe current NGS efforts in these areas.
