Satellite description[edit]
Thales Alenia Space,constructed Ekspress-80 payload, andISS Reshetnevconstructed thesatellite buswhich was based on theEkspress-1000N.The satellite has a mass of 1,947 kg (4,292 lb), provides 6.3 kilowatts to its payload, and a planned operational lifespan of 15 years. The satellite carried 38transponders:16 operating in theC-bandof the electromagnetic spectrum, 20 in theKu-bandand 2 in theL-band.[3]
Mission[edit]
The satellite is designed to provideTVandradio broadcastingservices,data transmission,multimediaservices,telephony,andmobile communications.[3]
Launch[edit]
Ekspress-80 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(16,593 km x 54,812 km x 0.62°), as wasEkspress-103(16,581 km x 5,4811 km x 0.64°).[4]
Mission[edit]
Roscosmos announced on 9 September 2020, that the Ekspress-80 satellite was damaged during its transfer to geostationary orbit, probably by space debris. However, the continuation of the transfer operations was not threatened. The satellite entered in service at orbital position 80° East on 15 March 2021.[1]
