Russia launched the Ekspress-AMU3 and AMU7 communications satellites on a Proton-M mission on 13 December 2021.

13 Dec 2021: Russia conducted a rare Proton-M launch from the Baikonur Cosmodrome. The mission lasted 18 hours to place the Ekspress-AMU3 and AMU7 communications satellites into supersynchronous GEO. Launch Video.

– Both the Ekspress AMU 3 and AMU 7 are in 16250 x 52888 km x 1.7° Supersynchronous Transfer Orbits.

– This is a very similar deployment orbit to the Ekspress 80 and 103 mission in 2020.

– Both satellites are GEO bound with a design life of 15 years. Both are carrying enough propellant to extend this 17 years.

Ekspress AMU3 carries 39 transponders; 30 of these operate in the Ku band of the electromagnetic spectrum. It will be stationed at 103° East and provide coverage over much of Russia as well as Kazakhstan. Ekspress AMU7 also carries 39 transponders; however, only 20 of these are Ku-band. From its station at 145° East, it will cover Siberia and far-eastern Russia.
