Recent Developments in at the CDDIS in Support of GGOS

Abstract:

The Crustal Dynamics Data Information System (CDDIS) supports data archiving and distribution activities for the space geodesy and geodynamics community. The main objectives of the system are to store space geodesy and geodynamics related data and products in a central data bank, to maintain information about the archival of these data, to disseminate these data and information in a timely manner to a global scientific research community and provide user based tools for the exploration and use of the archive. The CDDIS data system and its archive is a key component in several of the operational services within the International Association of Geodesy (IAG) and its observing system the Global Geodetic Observing System (GGOS), including the IGS, the International DORIS Service (IDS), the International Laser Ranging Service (ILRS), the International VLBI Service for Geodesy and Astrometry (IVS), and the International Earth Rotation and Reference Systems Service (IERS).

In early 2015, CDDIS enhanced its operations with a new search tool enabling users to quickly search the archives in both spatial and temporal parameters. Also, in partnership with the IGS Real Rime Service, CDDIS established a new GNSS real-time streaming service with over 150 data streams and 30 products streams to the GNSS community providing additional capability and redundancy to the IGS Real Time Service (RTS). This poster will showcase these enhancements and others that CDDIS has made over the past year for the geodetic community and describe future plans for the system.
