Mr. Larry D. Hothem is a senior physical scientist with the U.S. Geological Survey (USGS), Department of the Interior (DOI) who has served as a senior technical advisor on GNSS with his expertise focusing on the integration of GNSS with remote sensing technologies that supports the USGS earthscience programs, including collaborative geodetic science research activities in Antarctica for the past 30 years. In these efforts, he has served on numerous working groups and task forces, including supporting the U.S. Space-Based Positioning, Navigation and Timing (PNT) Systems Policy, the GPS modernization program, global geodetic reference systems, and serving as a member of the U.S. delegation participating in the annual meetings of the International Committee on GNSS (ICG), and UN Office of Outer Space Affairs (UNOOSA).

Serving as a USGS subject matter expert with a focus on geodesy, geopositioning, and remote sensing technologies, Mr. Hothem is active in development of national and international geospatial data and information standards, and serves as a member of project teams of Technical Committee 211, Geographic Information/Geomatics, and International Organization for Standardization (ISO). Appointed by the International Association of Geodesy (IAG), he serves as the Vice-Chair, Control Body, ISO Geodetic Registry.

In support of the U.S. Antarctica Research Programs, Mr. Hothem serves as the lead on planning and coordination for the high accuracy absolute gravity (AG) measurements project of the Polar Earth Observing Network (POLENET) program. The joint U.S.-France AG measurements project provide a means to answer critical questions about ice sheet behavior in a warming world. He is a member of the Scientific Committee on Antarctic Research (SCAR) Expert Group on Geodetic Infrastructure of Antarctica (GIANT).

Mr. Hothem has a BSc in Civil Engineering, University of Cincinnati, a Diploma in Electronic Engineering Technology, Capital Radio Engineering Institute, and has completed graduate courses in geodetic science at The George Washington University. He is an associate member and Fellow, International Association of Geodesy (IAG); past president and Fellow of ION; and recipient of the 1996 Surveying and Mapping Award, American Society of Civil Engineers (ASCE).
