It is positioned in geostationary orbit, and will be located at a longitude of 61.5° West, from where it is intended to provide direct broadcasting of high-definition television services to the continental United States and Puerto Rico for Dish Network.[2][3] EchoStar XV was built by Space Systems/Loral, and is based on the LS-1300 satellite bus. It is equipped with 32 J band (IEEE Ku band) transponders,[2] and at launch it had a mass of {{convert|5521|kg}}. It has a design life of fifteen years,;[3] however, it is carrying enough fuel for around twenty years of operations.[3] It has a common configuration with EchoStar XI and EchoStar XVI.[4] The launch of EchoStar XV was conducted by International Launch Services, using a Proton-M carrier rocket with a Briz-M upper stage. The launch occurred from Site 200/39 at the Baikonur Cosmodrome in Kazakhstan, at 18:40 UTC on 10 July 2010.[5] The launch successfully placed EchoStar XV into a geosynchronous transfer orbit.[6] Following separation from the rocket, it manoeuvred into a geostationary orbit with a perigee of {{convert|35781|km}} and an apogee of {{convert|35805|km}}.[7] See also{{Portal|Spaceflight}}
