The communication satellites Ekspress-80 and Ekspress-103 entered the target geo-transfer orbit, the press service of Roscosmos reported. The spacecraft separated from the Briz-M upper stage and entered a target orbit with an altitude of 54.9 thousand kilometres.
The Briz-M began launching two spacecraft into target orbits. It is noted that during the launch, 5 planned inclusions of its propulsion system were performed. Currently, both Russian telecommunications satellites have been taken over by the launch customer. The additional launch of the satellites is combined with bringing the spacecraft to the operating point, which makes it possible to shorten the time for their commissioning. The term for additional deployment of the Ekspress-80 satellite is no more than 152 days, and the Ekspress-103 satellite is no more than 160 days.
The satellites are Russian telecommunications spacecraft of the middle class. They are designed to provide fixed and mobile services, digital TV and radio broadcasting, high-speed access to the information and telecommunications network Internet, as well as data transmission in the Russian Federation and the CIS countries. It is noted that the spacecraft will have to work for at least 15 years. They include a payload designed for retransmission of digitally modulated signals received by the device both in continuous mode and in TDMA mode in single-signal and multi-signal modes.
