UNAVCO, a non-profit university-governed consortium, facilitates geoscience research and education using geodesy.
We challenge ourselves to transform human understanding of the changing Earth by enabling the integration of innovative technologies, open geodetic observations, and research, from pole to pole.


Geodesy is the study of Earth’s shape, gravity field, and rotation. Geodetic research defines the terrestrial reference frame; and quantifies changes in the properties of Earth’s surface and subsurface, ice sheets and glaciers, and oceans and atmosphere. Geodesy’s broader benefits include help with preparedness and mitigation of hazards; and foundational support for space-based operations, navigation, communications, surveying, resource management, and national security.

Community and Services

The UNAVCO consortium consists of more than 100 US academic Members and over 75 Associate Members (domestic and international). Through our Geodetic Infrastructure and Geodetic Data Services Programs, UNAVCO operates and supports geodetic networks, geophysical and meteorological instruments, a free and open data archive, software tools for data access and processing, cyberinfrastructure management, technological developments, technical support, and geophysical training. The UNAVCO Education and Community Engagement program provides educational materials, tools and resources for students, teachers, university faculty and the general public. We also provide summer internship experiences for undergraduate students interested in careers in geodesy and geosciences through our RESESS Program.

Offices and Staff

UNAVCO is headquartered in Boulder, Colorado with regional offices in San Clemente, California, Portland, Oregon, and Anchorage, Alaska. Geoscience and engineering staff are deployed on assignments throughout the United States and around the world with regular deployments in the Arctic and Antarctica. Core sponsorship for UNAVCO is provided by the National Science Foundation (NSF) and National Aeronautics and Space Administration (NASA).

Brief History

UNAVCO originated as the University NAVSTAR Consortium in 1984 within the Cooperative Institute for Research in Environmental Studies (CIRES) at the University of Colorado, Boulder. In 2001, UNAVCO, Inc, became an independent 501(c)(3) organization.
