The system broadcasts GPS-interoperable and augmentation signals as well as original Japanese signals from an inclined, elliptical geosynchronous orbit. Using this system, users around Japan and Oceania can use seamless positioning, navigation, and timing services, even in urban canyons and mountainous areas. A government policy supports the project to promote the use of geographical spatial information linked to satellite-based navigation for a wealthy and secure life in accordance with the rapid increase of satellite navigation users nationwide. To support that policy, JAXA is in charge of developing the first stage of QZSS in collaboration with related ministries and national institutes. Attention is devoted to making the system reliable and economical using legacy Japanese GEO satellite system technologies, not only satellite technology, but also ground systems and operations technologies."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670320506104578","@type":"Researcher","foaf:name":[{"@value":"Noriyasu Inaba"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320506104448","@type":"Researcher","foaf:name":[{"@value":"Akihiro Matsumoto"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320506104580","@type":"Researcher","foaf:name":[{"@value":"Hidemi Hase"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320506104579","@type":"Researcher","foaf:name":[{"@value":"Satoshi Kogure"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320506104576","@type":"Researcher","foaf:name":[{"@value":"Mikio Sawabe"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320506104577","@type":"Researcher","foaf:name":[{"@value":"Koji Terada"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00945765"}],"prism:publicationName":[{"@value":"Acta Astronautica"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"2009-10","prism:volume":"65","prism:number":"7-8","prism:startingPage":"1068","prism:endingPage":"1075"},"reviewed":"false","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:S0094576509001799?httpAccept=text/xml"},{"@id":"https://api.elsevier.com/content/article/PII:S0094576509001799?httpAccept=text/plain"}],"createdAt":"2009-04-20","modifiedAt":"2019-05-19","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360588380591389312","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Development of a Surface Charging Assessment System for the GEO Region by Combining Global Magnetosphere MHD and Spacecraft Charging Models"}]},{"@id":"https://cir.nii.ac.jp/crid/2051714792008790400","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Development of space environment customized risk estimation for satellites (SECURES)"}]},{"@id":"https://cir.nii.ac.jp/crid/2120870839328493184","@type":"OtherWorks","resourceType":"学術雑誌論文(journal article)","relationType":["isIdenticalTo"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Design concept of Quasi Zenith Satellite System"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1016/j.actaastro.2009.03.068"},{"@type":"OPENAIRE","@value":"doi_dedup___::47789316ce6b67f94e64d92d614366e7"},{"@type":"IRDB","@value":"oai:irdb.nii.ac.jp:01332:0004469663_isIdenticalTo_DOI_B3HOnvyWJJMEODj9quKEwmlyvK"},{"@type":"CROSSREF","@value":"10.1109/tps.2024.3519295_references_DOI_RjeOeKAbQj9krrLoFxuEegALci6"},{"@type":"CROSSREF","@value":"10.1186/s40623-021-01355-x_references_DOI_RjeOeKAbQj9krrLoFxuEegALci6"}]}
