It is a dual-use spacecraft: Telespazio will use some of the satellite's transmission capacity and some will be used by the Italian defense ministry and NATO. The spacecraft is based on the Italsat 3000 bus and includes one EHF/Ka band, three UHF-band and five active SHF-band transponders. It is designed to be operable for 13 years.[2] ConstructionThales Alenia Space was the prime contractor for development and construction of the SICRAL 1B satellite.[3]LaunchOn April 20, 2009 Sea Launch used a Zenit-3SL to carry SICRAL 1B into a geosynchronous transfer orbit. Liftoff from the Ocean Odyssey launch platform took place at 08:16 GMT.[4] References1. ^{{cite web|url=http://www.heavens-above.com/orbit.aspx?satid=34810|title=SICRAL 1B - Orbit|first=Chris|last=Peat|work=Heavens Above|date=25 October 2013|accessdate=29 October 2013}} {{Portal|Spaceflight}}{{Orbital launches in 2009}}{{Italy-spacecraft-stub}}2. ^{{cite web |url=http://www.sea-launch.com/news_releases/2009/nr_090416.html |title=Sea Launch Counts Down to SICRAL 1B Launch |publisher=Sea Launch |deadurl=yes |archiveurl=https://web.archive.org/web/20090419115317/http://www.sea-launch.com/news_releases/2009/nr_090416.html |archivedate=2009-04-19 |df= }} 3. ^{{cite web |url=http://www.thalesonline.com/space/Press-Room/Press-Release-search-all/Press-Release-search-result/Press-Release-Article.html?link=35751037-5a34-4a7c-5874-1b6e36251f22:central&locale=EN-gb&Title=Italian+satellite+SICRAL+1B+ready+for+launch+on+April+19&dis=1 |archive-url=https://archive.is/20130203171424/http://www.thalesonline.com/space/Press-Room/Press-Release-search-all/Press-Release-search-result/Press-Release-Article.html?link=35751037-5a34-4a7c-5874-1b6e36251f22:central&locale=EN-gb&Title=Italian+satellite+SICRAL+1B+ready+for+launch+on+April+19&dis=1 |dead-url=yes |archive-date=3 February 2013 |title=Italian satellite SICRAL 1B ready for launch on April 19 |publisher=Thales Alenia Space |date=9 April 2009 }} 4. ^{{cite web |url=http://www.sea-launch.com/news_releases/2009/nr_090420.html |title=Sea Launch Successfully Delivers SICRAL 1B Satellite to Orbit |date=April 20, 2009 |publisher=Sea Launch}} 5 : Artificial satellites orbiting Earth|Military satellites|Satellites of Italy|Spacecraft launched in 2009|Communications satellites of Italy |
