About satellites
"Express-80" and "Express-103" were built by order of the Federal State Unitary Enterprise "Space Communications" on the basis of the unified medium-class platform "Express-1000N" developed by "Information Satellite Systems". The company's partner for the payload of new satellites is traditionally the European company Thales Alenia Space.
The devices are designed to provide fixed and mobile communication services, digital TV and radio broadcasting, high-speed Internet access, as well as data transmission in Russia and the CIS countries in the C-, Ku - and L-bands. The payload will include 38 (for Express-80) and 37 (for Express-103) main transponders. The active life of the devices is 15 years.
As previously reported by the Federal State Unitary Enterprise "Space Communications", the satellites "Express-80" and "Express-103" are planned to be put into operation in January-February 2021.
