Our planet is dynamic and ever-changing, and so it seems, is our IGS Workshop planning process, as well. Due to circumstances beyond our control, we will unfortunately need to move our 2022 Workshop to a fully virtual format.
While we will all miss seeing each other in person, we will use this change of circumstances to help us refocus the IGS Workshop back to being just that – a community workshop. We will be operating on a compressed schedule to try to be inclusive to as many time zones as possible, and condensing our workshop program to aspects that are the most critical to the function of our Service, specifically a small number of keynote presentations by luminaries and innovators in our community, supported by a comprehensive agenda of working group and/or topical collaboration sessions. The emphasis will be on bringing our community together to discuss key issues and brainstorm the next steps toward a multi-GNSS IGS in service to our global community.
The virtual workshop will take place, as scheduled, the week of 27 June to 1 July, 2022. Key changes include:
- Live Keynote presentations
- Targeted WG/topical splinter sessions convened by IGS Working Group Chairs and community leaders
- Plenaries/posters will not be held during this workshop, but are effectively already taking place (virtually) via the Tour de l’IGS Mini Workshop Series; the next Tour de l’IGS is planned for late April.
- We will plan to hold additional/enhanced sessions at the December 2022 AGU for in-person presentations, an Open AM/WG Meeting, and 2022 Workshop networking event.
We hope that this proposed workshop program will help the IGS workshop return to its unique place among our regular meetings, adding value and impact to our profession.
Please check back periodically for additional event updates.

Director of Geodetic Infrastructure (GI) at UNAVCO, Inc
Glen S. Mattioli, Ph.D. is the Director of Geodetic Infrastructure (GI) at UNAVCO, Inc. (a 501(c)(3) non-profit corporation), which operates the Enabling Discoveries in Multiscale Earth System Dynamics: Geodetic Facility for the Advancement of Geoscience (GAGE) for the National Science Foundation, with additional core support from NASA and the USGS in Boulder, CO. Mattioli was a professor and now is an adjunct professor of Earth & Environmental Sciences at the University of Texas at Arlington; he was on assignment at UNAVCO from June 2012 through September 2015, when he became a full-time UNAVCO staff member. Prior to that he was a professor of Geosciences at the University of Arkansas, Fayetteville, and the University of Puerto Rico, Mayagüez. He was recently appointed as Research Professor in the Physics Department at the University of Colorado Denver.
In his role as the GI Director at UNAVCO, he oversees the planning, construction, operation and maintenance, and data flow of hemispherical-scale geodetic networks, including the Network of the Americas (NOTA), which federated the former EarthScope Plate Boundary Observatory, spanning the North American continent, COCONet throughout the Caribbean region, and TLALOCNet in Mexico. Other geodetic networks supported by the GI directorate include POLENet in Greenland (GNET) under contract with the Danish Government and Antarctica (ANET) as well as the NASA Global GNSS Network and the geodetic component of the USGS ShakeAlert earthquake early warning system. In addition, the GI program supports NSF, NASA, USGS, and community PIs with planning, logistics, engineering, and GNSS and TLS/UAV-SfM imaging instrumentation, as requested.
Mattioli received his BA from the University of Rochester in Geology, and his MS and PhD from Northwestern University, in Geological Sciences, before completing post-doctoral fellowships at Caltech and UC Berkeley. Glen has been doing tectonic and volcanic geodesy across the Caribbean since 1994. Glen resides with his wife, Pamela Jansma, and their two cats, Sammie and Sylvie in the Lower Highlands neighborhood of Denver.
Dr. Ying-Hwa “Bill” Kuo
Director of UCAR Community Programs
Dr. Bill Kuo is the Director of UCAR Community Programs. The University Corporation for Atmospheric Research (UCAR) is a non-profit consortium of 123 North American member colleges and universities focused on research and training in the atmospheric and related Earth System Sciences. UCAR Community Programs provide education, training, data and science support services to the broad Earth science community.
Dr. Kuo started his career as a NCAR scientist working on mesoscale meteorological modeling. Dr. Kuo served as the Director of the Developmental Testbed Center (DTC) from 2009 to 2018. In that capacity, he interacted closely with research and operational numerical weather prediction (NWP) communities to facilitate the transition of new NWP advances into operations. From 1997 through 2015, Dr. Kuo served as the Director of the UCAR COSMIC (Constellation Observing System for Meteorology, Ionosphere, and Climate) Program. COSMIC was a joint Taiwan-U.S. satellite mission, which was called FORMOSAT-3 in Taiwan. COSMIC was the world’s first GPS radio occultation satellite constellation, which provides critical observations to support atmospheric research and operational weather prediction. The follow-on mission, FORMOSAT-7/COSMIC‑2, was launched in June 2019.
Dr. Kuo has mentored more than 25 graduate students 20 postdoctoral fellows. He has published over 200 journal papers, as well as numerous conference articles and reports. His scientific interests include hurricanes, extratropical cyclones, mesoscale convective systems, heavy rainfall prediction, data assimilation, and GPS atmospheric remote sensing and their research applications.
Dave Hatch
GPSIIIF Program Management Director and Navigation and Systems Mission Area Deputy of Lockheed Martin Space
Dave Hatch is the GPSIIIF Program Management Director and Deputy Mission Area Lead for LM Space where he is responsible to deliver the follow-on GPSIII Space Vehicles on time, and within budget. The program has 7 production vehicles on contract with more to be awarded at the end of this year. Just prior to this role he served as the Chief Engineer for Navigation Systems Mission Area. His role was to ensure the technical quality of all Navigation Systems products and lead the evolution of future PNT mission solutions. His highlights were delivering the first two GSPIII satellites into space and ensuring a steady production rhythm for GPSIII and a solid design for GPSIIIF.
He began his career in 2003 working Controls and Sensing as an analyst and Hardware Engineer on the Airborne Laser Program where he led a team of engineers to successfully shoot-down a boosting missile with a Mega-watt class LASER flying on a Boeing 747. In 2012 he transferred to Denver to support Special Programs line of business where the highlight for him was managing the design, build and flight test of two demonstration payloads in less than 10 months, both on time and under budget.
Dave holds a Bachelor’s of Science Degree in Applied Physics from the University of Utah, and a Master’s of Science degree in Computer Science Systems Engineering from the University of Denver.

Frequently Asked Questions (FAQ)
General
Why is this year’s workshop virtual?
Our planet is dynamic and ever-changing, and so it seems, is our IGS Workshop planning process, as well. Due to circumstances beyond our control, we will unfortunately need to move our 2022 Workshop to a fully virtual format. While we will all miss seeing each other in person, we will use this change of circumstances to help us refocus the IGS Workshop back to being just that – a community workshop. The emphasis will be on bringing our community together to discuss key issues and brainstorm the next steps toward a multi-GNSS IGS in service to our global community. We hope that this proposed workshop program will help the IGS workshop return to its unique place among our regular meetings, adding value and impact to our profession.

We will plan to hold additional/enhanced sessions at the December 2022 AGU for in-person presentations, an Open AM/WG Meeting, and 2022 Workshop networking event.
If I have any additional questions, who can I contact?
For technical questions, contact your session moderator. For session questions, contact the session convener. For workshop questions, contact the local and scientific organizers (workshop@igs.org) or the Central Bureau (cb@igs.org).
