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 various DORIS products from data generated by the DORIS beacons supporting the IDS network. These products include orbits of satellites with DORIS receivers onboard. These orbit products are available in SP1 or SP3 orbit format.", "distribution": [{"@type": "dcat:Distribution", "description": "Search results for publications that cite this dataset by its DOI.", "downloadURL": "https://scholar.google.com/scholar?q=10.5067%2FDORIS%2FDORIS_IDSORB_001", "format": "HTML", "mediaType": "text/html", "title": "Google Scholar search results"}, {"@type": "dcat:Distribution", "description": "URL for more information about DORIS products", "downloadURL": "http://doi.org/10.5067/DORIS/DORIS_IDSORB_001", "format": "HTML", "mediaType": "text/html", "title": "This dataset's landing page"}, {"@type": "dcat:Distribution", "description": "URL for retrieval of DORIS products through https", "downloadURL": "https://cddis.nasa.gov/archive/doris/products/orbits", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset"}], "identifier": "C1602851234-CDDIS", "issued": "1993-01-01", "keyword": ["earth-science", "geodetics", "gravity-gravitational-field", "solid-earth", "tectonics"], "landingPage": "https://doi.org/10.5067/DORIS/DORIS_IDSORB_001", "language": ["en-US"], "modified": "2025-07-17", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "CDDIS"}, "spatial": "-180.0 -90.0 180.0 90.0", "temporal": "1992-01-01T00:00:00Z/2025-03-24T00:00:00Z", "theme": ["IDS", "geospatial"], "title": "Ground-Based Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS) Satellite Orbit Product from NASA CDDIS"}
