Ekspress-103 (Russian: Экспресс-103 meaning Express-103) is a Russian communications satellite which was launched in 2020. Part of the Ekspress series of geostationary communications satellites, it is owned and operated by the RSCC Space Communications.

Satellite description[]

Thales Alenia Space, constructed Ekspress-103 payload, and ISS Reshetnev constructed the satellite bus which was based on the Ekspress-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 37 transponders: 16 operating in the C-band of the electromagnetic spectrum, 20 in the Ku-band and 1 in the L-band.[3]

Mission[]

The satellite is designed to provide TV and radio broadcasting services, data transmission, multimedia services, telephony, and mobile communications.[3]

Launch[]

Ekspress-103 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 (16,581 km x 5,4811 km x 0.64°) as was Ekspress-80 (16,593 km x 54,812 km x 0.62°).[4]

Mission[]

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