Yamal-601 (Russian: {{lang|ru|Ямал-601}}) is a Russian geostationary communications satellite ordered by Gazprom Space Systems from Thales Alenia Space (TAS) on the Spacebus-4000C4 satellite bus for its Yamal programme. The satellite has mass of {{cvt|5422|kg}} and 11 kW of payload power with over 15 years of design life.{{cite web|url=https://www.thalesgroup.com/en/worldwide/space/press-release/yamal-601-satellite-orbit |title=Yamal-601 satellite in orbit|publisher=Thales Alenia Space|date=31 May 2019|access-date=23 July 2020}} Its payload was also supplied by Thales Alenia Space and is composed of 38 C-band and 32 Ka-band transponders.{{cite web|url=https://www.gazprom-spacesystems.ru/en/infrastructure/?ELEMENT_ID=9068|title=Yamal-601 49° East|publisher=Gazprom|access-date=26 April 2021}} It replaced Yamal-202 on 49° East as Yamal-202 was slated to reach its end of service around 2019.
History
In 2013, Gazprom Space Systems Board decided on a new plan. It required two new spacecraft: Yamal-501 and Yamal-601. In January 2014, Gazprom and Thales announced a contract for a new spacecraft, Yamal-601.{{cite web|url=http://space.skyrocket.de/doc_sdat/yamal-601.htm|title=Yamal-601|publisher=Gunter's Space Page |date=11 June 2019|access-date=26 April 2021}} In 2015, the Yamal-401 history would repeat itself, and the contract of Yamal-601 with Thales was cancelled and was reassigned to ISS Reshetnev, but Thales was again allowed to keep the payload supply. However, in 2016, this decision to give the spacecraft bus development contract to ISS Reshetnev was reversed, and Thales Alenia Space ended up developing and building the whole satellite, bus and payload.{{cite web|last1=Zak|first1=Anatoly |title=Proton launches Yamal-601|url=http://www.russianspaceweb.com/yamal601.html|publisher=RussiaSpaceWeb.com|access-date=4 June 2019}}
Launch
The satellite was launched on 30 May 2019, at 17:42:00 UTC.{{cite web|url=http://tass.com/science/1060952|title=Proton-M puts Yamal-601 satellite in suborbital trajectory|publisher=TASS|date=30 May 2019|access-date=26 April 2021}} On 24 June 2019, the satellite was inserted into nominal geostationary orbit.{{cite web|url=https://www.thalesgroup.com/en/worldwide/space/press-release/yamal-601-communications-satellite-now-geostationary-orbit|title=YAMAL-601 COMMUNICATIONS SATELLITE NOW IN GEOSTATIONARY ORBIT |publisher=Thales Alenia Space|date=24 June 2019|access-date=26 April 2021}}
Mission
The satellite is intended for the replacement of the Yamal-202 satellite and business development in the Ka-band. On 19 July 2019, the satellite was finally put into operation, transferring all the networks from the Yamal-202 satellite to it.{{cite web|url=https://www.thalesgroup.com/en/worldwide/space/press-release/thales-alenia-space-build-yamal-601-satellite-gazprom-space-systems|title=Thales Alenia Space to build Yamal-601 satellite for Gazprom Space Systems|publisher=Thales Alenia Space|date=22 January 2014|access-date=26 April 2021}}
