EchoStar XXI (formerly known as TerreStar 2) is a European communications satellite which is operated by Echostar Corporation. It was constructed by Space Systems/Loral, based on the SSL 1300 satellite bus, and carries S band transponders which will be used to provide 2 GHz mobile connectivity throughout Europe. EchoStar XXI was launched at 03:45 UTC on June 8, 2017 from the Baikonur Cosmodrome in Kazakhstan. This satellite was the heaviest commercial payload flown aboard a Russian booster at the time of its launch.

| - EchoStar 21 (EchoStar XXI, TerreStar 2) ist ein kommerzieller Kommunikationssatellit des US-amerikanischen Unternehmens EchoStar. Er wurde am 8. Juni 2017 um 3:45 UTC mit einer Proton/Bris-M-Trägerrakete vom Raketenstartplatz Baikonur in eine geostationäre Umlaufbahn gebracht. Der dreiachsenstabilisierte Satellit ist mit einem 2-GHz-S-Band-Transponder und einem großen Reflektor ausgerüstet und soll von der Position 10,25° Ost aus Europa mit Mobilfunk versorgen. Er wurde auf Basis des Satellitenbusses SSL 1300 der Space Systems Loral gebaut und besitzt eine geplante Lebensdauer von 15 Jahren. Der Satellit verwendet den ETSI-GMR-1-3G-Standard für Luftschnittstellen, um es mobilen Drahtlosgeräten zu ermöglichen, über den Satelliten im S-Band zu kommunizieren. Die Kommunikation zum Satelliten erfolgt im Ka-Band. (de)
