European VLBI Network Data Archive

EVN Data Archive

Subject(s)
Content type(s)
Country
The European VLBI Network (EVN) is an interferometric array of radio telescopes located primarily in Europe and Asia, with additional telescopes in South Africa and Puerto Rico. The EVN performs high-resolution observations of cosmic radio sources at wavelenghts from 92cm to 7mm. The EVN Data Archive contains, among other things, the correlated data from EVN observations plus pipeline output, including the initial calibration tables to apply to the correlated data and preliminary images. In general, the correlated data and some pipeline results are proprietary for one year following distribution to the PI of the final epoch of observations resulting from a proposal after which the data enters the public domain; more details are in the "EVN Data Access Policy" linked via the archive-introduction page.

Crustal Dynamics Data Information System

CDDIS

Subject(s)
Content type(s)
Country
The Crustal Dynamics Data Information System (CDDIS) was initially developed to provide a central data bank for NASA's Crustal Dynamics Project (CDP). 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 products in a central data bank, to maintain information about the archival of these data, and to disseminate these data and information in a timely manner to NASA investigators and cooperating institutions.

GNSS - ISDC

Global Navigation Satellite Systems - Information System and Data Center

Subject(s)
Content type(s)
Country
The term GNSS (Global Navigation Satellite Systems) comprises the different navigation satellite systems like GPS, GLONAS and the future Galileo as well as rawdata from GNSS microwave receivers and processed or derived higher level products and required auxiliary data. The results of the GZF GNSS technology based projects are used as contribution for maintaining and studying the Earth rotational behavior and the global terrestial reference frame, for studying neotectonic processes along plate boundaries and the interior of plates and as input to short term weather forecasting and atmosphere/climate research. Currently only selected products like observation data, navigation data (ephemeriden), meteorological data as well as quality data with a limited spatial coverage are provided by the GNSS ISDC.

International VLBI Service for Geodesy and Astrometry of NASA

IVS

Subject(s)
Content type(s)
Country
IVS is an international collaboration of organizations which operate or support Very Long Baseline Interferometry (VLB I) components. The service aspect of IVS is meant to serve both outside users and the geodetic and astrometric community itself. Both the contributors and users of data will be served.
