NASA's Crustal Dynamics Data Information System (CDDIS), one of NASA's Distributed Active Archive Centers (DAACs), provides data and information to support the international space geodesy community. CDDIS is part of the Earth Sciences Division at NASA's Goddard Space Flight Center in Greenbelt, MD, and serves as one of the core components for the geometric services established under the International Association of Geodesy (IAG), an organization that promotes scientific cooperation and research in geodesy on a global scale.
CDDIS provides continuous, long term, public access to the data and derived products from a global network of observing stations equipped with one or more of the following measurement techniques:
- Global Navigation Satellite System (GNSS)
- Satellite Laser Ranging (SLR)
- Very Long Baseline Interferometry (VLBI)
- Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS)
