DORIS is a dual-frequency Doppler system consisting of a receiver flying aboard a satellite and a globally distributed network of ground beacons. The DORIS receiver on-board the orbiting satellite tracks the dual-frequency radio signals transmitted by the network of ground beacons and generates the DORIS data. A measurement is made of either the Doppler shift or absolute phase as the satellite\u2019s orbit moves over the ground-based beacon. DORIS data records contain a time-tagged range-rate measurement with associated ancillary information. DORIS observations from a global network can be utilized for a variety of products. Analysis Centers (ACs) of the International DORIS Service (IDS) retrieve DORIS data on a regular basis to compute weekly station position solutions for the DORIS beacons supporting the IDS network. The IDS Analysis Center Coordinator combines these individual AC solutions in a standard least-squares adjustment to generate the official IDS weekly combined station position solution.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://cddis.nasa.gov/archive/doris/products/sinex_series", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://www.earthdata.nasa.gov/data/space-geodesy-techniques/doris/reference-frame-products", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "http://doi.org/10.5067/DORIS/DORIS_IDSWEEKLYSNX_001", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "conformsTo": "http://www.isotc211.org/2005/gmi", "description": "The metadata's original source.", "downloadURL": "https://cmr.earthdata.nasa.gov/search/concepts/C1544924806-CDDIS.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "10.5067/DORIS/DORIS_IDSWEEKLYSNX_001", "keyword": ["earth-science-geodetics-solid-earth-coordinate-reference-system-country-regional-coordinate-ref", "earth-science-geodetics-solid-earth-coordinate-reference-system-global-coordinate-reference-sys", "earth-science-geodetics-solid-earth-ellipsoid-characteristics", "earth-science-geodetics-solid-earth-geoid-characteristics", "earth-science-gravity-gravitational-field-solid-earth-control-surveys", "earth-science-gravity-gravitational-field-solid-earth-gravity", "earth-science-gravity-gravitational-field-solid-earth-polar-motion-annual-elliptical-component", "earth-science-gravity-gravitational-field-solid-earth-polar-motion-chandler-circular-component", "earth-science-gravity-gravitational-field-solid-earth-rotational-motion-variations-rotational-r", "earth-science-gravity-gravitational-field-solid-earth-satellite-orbits-revolution-angle-of-elev", "earth-science-gravity-gravitational-field-solid-earth-satellite-orbits-revolution-angle-of-incl", "earth-science-gravity-gravitational-field-solid-earth-satellite-orbits-revolution-orbit-type", "earth-science-gravity-gravitational-field-solid-earth-satellite-orbits-revolution-orbit-velocit", "earth-science-gravity-gravitational-field-solid-earth-satellite-orbits-revolution-orbital-posit", "earth-science-tectonics-solid-earth-earthquakes-earthquake-magnitude-intensity", "earth-science-tectonics-solid-earth-plate-tectonics-crustal-motion-crustal-motion-direction", "earth-science-tectonics-solid-earth-plate-tectonics-crustal-motion-crustal-motion-rate", "earth-science-tectonics-solid-earth-plate-tectonics-fault-movement-fault-movement-direction", "earth-science-tectonics-solid-earth-plate-tectonics-fault-movement-fault-movement-rate", "earth-science-tectonics-solid-earth-plate-tectonics-plate-boundaries", "earth-science-tectonics-solid-earth-plate-tectonics-strain"], "license": "https://www.usa.gov/government-works", "modified": "2026-04-06", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "CDDIS"}, "spatial": "[[{\"EastBoundingCoordinate\":180,\"NorthBoundingCoordinate\":90,\"SouthBoundingCoordinate\":-90,\"WestBoundingCoordinate\":-180}],\"CARTESIAN\"]", "temporal": "1992-01-01/2026-03-30", "theme": ["Earth Science"], "title": "Ground-Based Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS) IDS Weekly Station Position Product from NASA CDDIS"}
