Course Availability

This course is only available to trainees 365 days after purchase. It would need to be repurchased by the trainee if not completed in the allotted time period. This course is no longer available. You will need to repurchase if you wish to take the course again.

Description

Geospatial practitioners have several methods to produce precise and accurate data from GNSS. However, there are many facets of GNSS positioning that might lead them to selecting one method over another depending on their needs. This session will compare static GNSS methods with real time methods and the precisions available from each one. A real world static GPS project for a county-wide height modernization network will be presented as it followed the NGS 58 & 59 guidelines for GPS derived ellipsoid heights and GPS derived orthometric heights, respectively. A summary of real time guidelines will be shown along with a discussion on site localization that is recommended for vertical data from a real time GNSS network (RTN). (For a thorough discussion of real time methods and important considerations the practitioner is referred to the four part GeoLearn series on real time GNSS positioning). Finally, static data from the NGS OPUS-S and OPUS-RS programs will be evaluated with a tip on editing Rinex data to submit to both of the programs.

Objectives

Objectives
Upon completion of this course, the student will be exposed to:
• Heights from the NGS data sheet
• Considerations for choosing RT or static procedures for your site control work
• Using NGS 58 & 59 guidelines for HTMOD or large projects using a real world example for planning, field requirements, data processing, and adjustment
• The RTN alternative to static work
• Localization to site control
• The four cardinal rules for RT positioning and the NGS RT guidelines

He has been actively involved with education/outreach to the geospatial community for almost 20 years, presenting over 100 talks and workshops on surveying and GNSS technology. Mr. Henning has authored articles for professional journals and trade magazines on GNSS positioning as well as authoring an extensive guideline document on single base real-time GNSS positioning and editing a real-time network guideline document while working at NOAA’s National Geodetic Survey (NGS). He has been the project lead for new height modernization geodetic networks in county-wide projects in the U.S., where he planned, helped construct, processed, adjusted and managed new geodetic control systems. Mr. Henning is Past President of the American Association for Geodetic Surveying (AAGS) and is an ACSM/AAGS Fellow. He has been presented with the NOAA Administrator’s Award for outstanding accomplishment in producing real time GNSS guidelines. He was awarded the Maryland Society of Surveyors “Surveyor of the Year” for 2013-14.
