GeoLearn, a company focused on serving the geospatial industry with online learning and continuing education credits, is proud to announce that nationally recognized geospatial expert Bill Henning's seven new GNSS courses have been added to the GeoLearn course catalog. Bill Henning is a professional land surveyor who was instrumental in developing RTK guidelines for surveyors at the National Geodetic Survey (NGS). Here he expands on the basics of positioning with RTK and adds a special three-course series on heighting with GNSS.
Henning's four courses on RTK dissect how GNSS works, covering the physics and surveying implications of what affects the signals from space, benefits and costs of single base versus real time networks, and best field methods to maximize a surveyor's effectiveness with RTK.
His heighting series (three courses) cover the interrelationships between gravity and heights, use of the NGS hybrid geoid model and height modernization procedures, and use of the NGS 58 and 59 guidelines and real-time precision. "I've tried to incorporate the very latest in the science and practical knowledge that many have developed at NGS in collaboration with public and private partners on the subject of effective RTK use and heighting with GNSS," said Henning.
"We were so pleased when Bill agreed to teach this series of courses," said Joe Paiva, CEO of GeoLearn. "Bill is a national treasure to surveyors and we are pleased to be able to extend his legacy to the public beyond his tenure with NGS."
