Crustal Dynamics Data Information System (CDDIS)

NASA's Crustal Dynamics Data Information System (CDDIS) is NASA’s data archive and information service supporting the international space geodesy community. CDDIS is part of the Solar System Exploration Division at NASA's Goddard Space Flight Center in Greenbelt, MD. CDDIS 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),
• Lunar Laser Ranging (LLR),
• Very Long Baseline Interferometry (VLBI), and
• Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS)
