r3d100010508 International Laser Ranging Service ILRS https://ilrs.cddis.eosdis.nasa.gov/ The International Laser Ranging Service (ILRS) provides global satellite and lunar laser ranging data and their related products to support geodetic and geophysical research activities as well as IERS products important to the maintenance of an accurate International Terrestrial Reference Frame (ITRF). The service develops the necessary global standards/specifications and encourages international adherence to its conventions. The ILRS is one of the space geodetic services of the International Association of Geodesy (IAG). The ILRS collects, merges, archives and distributes Satellite Laser Ranging (SLR) and Lunar Laser Ranging (LLR) observation data sets of sufficient accuracy to satisfy the objectives of a wide range of scientific, engineering, and operational applications and experimentation. https://ilrs.cddis.eosdis.nasa.gov/about/contact_ilrs/index.html ilrs-dc@lists.nasa.gov disciplinary 1998 eng 3 Natural Sciences 315 Geophysics and Geodesy 31502 Geodesy, Photogrammetry, Remote Sensing, Geoinformatics, Cartogaphy 34 Geosciences (including Geography) https://ilrs.cddis.eosdis.nasa.gov/missions/mission_support/index.html Plain text Raw data Scientific and statistical data formats Software applications serviceProvider earth's gravity field geodesy geophysics gravitation lunar laser ranging navigation polar motion remote sensing satellite space Goddard Space Flight Center USA general technical non-profit https://www.nasa.gov/goddard https://www.nasa.gov/content/contact-goddard ICSU World Data System WDS AAA general non-profit http://icsu-wds.org/ International Association of Geodesy IAG AAA funding non-profit http://www.iag-aig.org/ International Association of Geodesy, Global Geodetic Observing System GGOS AAA general non-profit http://176.28.21.212/en/about/ggos-infos/ http://176.28.21.212/en/about/contact/ National Aeronautics and Space Administration NASA USA funding non-profit https://www.nasa.gov/ ILS Terms of Reference https://ilrs.cddis.eosdis.nasa.gov/about/termsofref.html open open other https://www.nasa.gov/multimedia/guidelines/index.html closed unknown ftp://edc.dgfi.tum.de/ ftp://cddis.gsfc.nasa.gov/ none https://ilrs.cddis.eosdis.nasa.gov/about/cite.html unknown unknown ILRS is a network member of ICSU World Data System.
