The Crustal Dynamics Data Information System (CDDIS) supports the space geodesy and geodynamics community through NASA's Space Geodesy Project as well as NASA's Earth Science Enterprise. The CDDIS was established in 1982 at NASA's Goddard Space Flight Center as a dedicated data bank to archive and distribute space geodesy related data sets. Today, the CDDIS archives and distributes mainly Global Navigation Satellite Systems (GNSS, currently Global Positioning System GPS and GLObal NAvigation Satellite System GLONASS), laser ranging (both to artificial satellites, SLR, and lunar, LLR), Very Long Baseline Interferometry (VLBI), and Doppler Orbitography and Radio-positioning Integrated by Satellite (DORIS) data for an ever increasing user community of geophysicists. The CDDIS serves as a global data center for the International GNSS Service (IGS) since 1992, the International Laser Ranging Service (ILRS), the International VLBI Service for Geodesy and Astrometry (IVS), International DORIS Service (IDS), and the International Earth Rotation and Reference Systems Service (IERS). General information, including summary reports, data set documentation, etc., are available through the CDDIS archive.
