Ekspress-103(Russian:Экспресс-103meaningExpress-103) is a Russiancommunications satellitewhich was launched in 2020. Part of theEkspressseries ofgeostationarycommunications satellites, it is owned and operated by theRSCC Space Communications.

Description[edit]

Thales Alenia Space,constructed Ekspress-103 payload, andISS Reshetnevconstructed thesatellite buswhich was based on theEkspress-1000N.The satellite has a mass of 2,050 kg (4,520 lb), provides 6.3 kilowatts to its payload, and a planned operational lifespan of 15 years. The satellite carried 37transponders:16 operating in theC-bandof the electromagnetic spectrum, 20 in theKu-bandand 1 in theL-band.[3]

The satellite is designed to provideTVandradio broadcastingservices,data transmission,multimediaservices,telephony,andmobile communications.[3]

Ekspress-103 was originally to be launched in 2018, but was delayed to 2020. It used aProton-M/Briz-Mlaunch vehicleto be placed in asupersynchronous geostationary transfer orbit(16,581 km x 5,4811 km x 0.64°) as wasEkspress-80(16,593 km x 54,812 km x 0.62°).[4]

The Ekspress-103 satellite entered in service at orbital position 96.5° East on 25 March 2021, where it replacedEkspress-AM33.[1]
