Satellite description edit
Thales Alenia Space, constructed Ekspress-80 payload, and ISS Reshetnev constructed the satellite bus which was based on the Ekspress-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 38 transponders: 16 operating in the C-band of the electromagnetic spectrum, 20 in the Ku-band and 2 in the L-band.[3]
Mission edit
The satellite is designed to provide TV and radio broadcasting services, data transmission, multimedia services, telephony, and mobile communications.[3]
Launch edit
Ekspress-80 was originally to be launched in 2018, but was delayed to 2020. It used a Proton-M / Briz-M launch vehicle to be placed in a supersynchronous geostationary transfer orbit (16,593 km x 54,812 km x 0.62°), as was Ekspress-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]
