Launch Notes

The final of 5 burns by the Briz-M upper stage was cut short, leaving the payloads in a lower-than-intended orbit. It is not known to this day if the satellites will have to perform maneuvers to correct the orbit or not, if it's not the case, this flight will be later requalified as "success".

Ekspress-AMU7

Wiki

The Ekspress-AMU 7 spacecraft is designed to operate in an orbital position of 145 ° east longitude and is equipped with 16 active and two additional transponders operating through the use of backup equipment in the C-band, 20 active transponders in the Ku-band and 1 active transponder in the L band. The device includes a payload designed for reception, low-noise amplification, and frequency conversion of the received signal, in accordance with the channel bandwidth, as well as re-transmission of the received signal. The satellite is built on the Ekspress-1000N satellite bus produced by ISS Reshetnev and the payloads are of Thales Alenia Space
