One of the main component that has to be flexible, and reconfigurable is the beamforiming function that in todays satellite deployment are fixed to a regular grid of beams generated by regular lattice antennas.\nThe standout feature of the EMMANUELE project\u2019s solution is its reconfigurability, freeing it from the constraints of traditional regular beam frameworks\u2014a significant limitation in current systems such as Starlink. This adaptability enables dynamic coverage adjustments, optimising network performance and resource utilisation while significantly reducing the satellite\u2019s mass, power consumption, and costs.\n\nThe EMMANUELE project has two primary objectives:\n1) The overarching goal is to innovate and rigorously test a new generation of power-efficient digital beamforming techniques. These techniques are specifically designed to overcome the limitations of traditional Fast Fourier Transform (FFT) methods, which require uniformity.\n2) The project aims to create a digital beamforming solution fully compatible with irregular antenna arrays and non-standard beam lattice configurations. A key feature of this approach is its ability to provide comprehensive steering flexibility across a large number of beams. This directly addresses the unique challenges of non-geostationary satellite communication (satcom) systems, which often contend with the limited power and mass capacities of smaller satellite platforms.\n","rp_start_date":"2024-11-18 09:59:00","rp_duration":30,"rp_main_funder":"EUROPEAN SPACE AGENCY","rp_other_funders":["FNR"],"rp_external_partners":[],"rp_keywords":["Beamforming","Satellite Communications","Onboard Processors","Antenna Design"],"rp_members":[{"name":"Juan Carlos MERLANO DUNCAN","isPI":true,"isExternal":false,"featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwMjE3NzFfX0p1YW4gQ2FybG9zIE1FUkxBTk8gRFVOQ0FO","detailsPageUrl":"https:\/\/www.uni.lu\/snt-en\/people\/juan-carlos-merlano-duncan\/","id":"50021771"},{"name":"Juan Andres VASQUEZ-PERALVO","isPI":false,"isExternal":false,"featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwNDcwNTBfX0p1YW4gQW5kcmVzIFZBU1FVRVotUEVSQUxWTw==","detailsPageUrl":"https:\/\/www.uni.lu\/snt-en\/people\/juan-andres-vasquez-peralvo\/","id":"50047050"},{"name":"Luis Manuel GARCES SOCARRAS","isPI":false,"isExternal":false,"featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwNTc5NTVfX0x1aXMgTWFudWVsIEdBUkNFUyBTT0NBUlJBUw==","detailsPageUrl":"https:\/\/www.uni.lu\/snt-en\/people\/luis-manuel-garces-socarras\/","id":"50057955"},{"name":"Vu Nguyen HA","isPI":false,"isExternal":false,"featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwNDM5MzhfX1Z1IE5ndXllbiBIQQ==","detailsPageUrl":"https:\/\/www.uni.lu\/snt-en\/people\/vu-nguyen-ha\/","id":"50043938"},{"name":"Ti Ti NGUYEN","isPI":false,"isExternal":false,"featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwODY1MTVfX1RpIFRpIE5HVVlFTg==","detailsPageUrl":"https:\/\/www.uni.lu\/snt-en\/people\/ti-ti-nguyen\/","id":"50086515"},{"name":"Raudel CUIMAN MARQUEZ","isPI":false,"isExternal":false,"featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwODUwNDJfX1JhdWRlbCBDVUlNQU4gTUFSUVVFWg==","detailsPageUrl":"https:\/\/www.uni.lu\/snt-en\/people\/raudel-cuiman-marquez\/","id":"50085042"},{"name":"Ulan MYRZAKHAN","isPI":false,"isExternal":false,"featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwODkxOTVfX1VsYW4gTVlSWkFLSEFO","detailsPageUrl":"https:\/\/www.uni.lu\/snt-en\/people\/ulan-myrzakhan\/","id":"50089195"},{"name":"Vibhum SINGH","isPI":false,"isExternal":false,"featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwNDcwOTFfX1ZpYmh1bSBTSU5HSA==","detailsPageUrl":"https:\/\/www.uni.lu\/snt-en\/people\/vibhum-singh\/","id":"50047091"}]},"research-project-status":[],"research-project-type":[263],"field-of-interest":[281],"organisation":[186,184,195],"authorship":[326],"acf":[],"_links":{"self":[{"href":"https:\/\/www.uni.lu\/snt-en\/wp-json\/wp\/v2\/core-researches\/14211"}],"collection":[{"href":"https:\/\/www.uni.lu\/snt-en\/wp-json\/wp\/v2\/core-researches"}],"about":[{"href":"https:\/\/www.uni.lu\/snt-en\/wp-json\/wp\/v2\/types\/core-researches"}],"author":[{"embeddable":true,"href":"https:\/\/www.uni.lu\/snt-en\/wp-json\/wp\/v2\/users\/326"}],"version-history":[{"count":2,"href":"https:\/\/www.uni.lu\/snt-en\/wp-json\/wp\/v2\/core-researches\/14211\/revisions"}],"predecessor-version":[{"id":14213,"href":"https:\/\/www.uni.lu\/snt-en\/wp-json\/wp\/v2\/core-researches\/14211\/revisions\/14213"}],"wp:authorship":[{"embeddable":true,"href":"https:\/\/www.uni.lu\/snt-en\/wp-json\/wp\/v2\/users\/326"}],"wp:attachment":[{"href":"https:\/\/www.uni.lu\/snt-en\/wp-json\/wp\/v2\/media?parent=14211"}],"wp:term":[{"taxonomy":"research-project-status","embeddable":true,"href":"https:\/\/www.uni.lu\/snt-en\/wp-json\/wp\/v2\/research-project-status?post=14211"},{"taxonomy":"research-project-type","embeddable":true,"href":"https:\/\/www.uni.lu\/snt-en\/wp-json\/wp\/v2\/research-project-type?post=14211"},{"taxonomy":"field-of-interest","embeddable":true,"href":"https:\/\/www.uni.lu\/snt-en\/wp-json\/wp\/v2\/field-of-interest?post=14211"},{"taxonomy":"organisation","embeddable":true,"href":"https:\/\/www.uni.lu\/snt-en\/wp-json\/wp\/v2\/organisation?post=14211"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
