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.

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]

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

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]

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