Yamal-200s in the Energia orbit

November 26, 2018

November 24 marked the 15th anniversary of the launch of two Russian communications satellites Yamal-200. They were developed and built at Energia corporation on the basis of the in-house designed multi-purpose satellite bus under a contract with Gascom.

Yamal-200 spacecraft is a more powerful version of the spacecraft (SC) that became a part of the Yamal satellite communications and broadcasting system, than Yamal-100 SC which at that time had already been in operation in the geostationary orbit.

Yamal-200s that were intended for transmissions of large amounts of data began to provide state-of-the-art types of communications links to companies in the Russian gas industry, and to provide telecommunications services to users in Russia and abroad. It was in part owing to them that it became possible to use high-quality phone and fax links, videoconferencing, to transmit digital data and TV broadcasts, to access the internet.

It was not by accident that Energia corporation responded to the growing world market demand for high-quality telecommunications services. Way back at the time of S.P.Korolev it was here that the first Soviet communications satellite Molniya was built. Work on the Yamal project marked the Corporations comeback into the field of unmanned spacecraft for various applications.

In order to manufacture the Yamals, work was done to prepare the production facilities to meet international requirements and standards. Put into operation were an assembly and testing center, a work shop with clean-room environment (unparalleled in our countrys rocket and space industry). The test facilities allowed to run all kinds of tests on the assembled spacecraft: strength tests, vibration tests, acoustic tests, thermal vacuum tests, integrated electrical tests, etc.

Work on Yamal-200 incorporated to the maximum extent possible the experience gained in the development and operation of Yamal-100, but it also used innovative engineering solutions, which improved the SC reliability and longevity.

The appraisal of the work done in this area by the Energia work team was given by the time itself. The Yamal-100 SC stayed in orbit from September 6, 1999 to August 2011, for the first time exceeding the 10-year design life in geostationary orbit. The design life in orbit was also exceeded by one of the Yamal-200 SC (Yamal-202), which is still operational. According to Gascom, hardware operational life and propellant supply margins will allow Yamal-202 to operate in a stable condition till mid-2019, when it will be replaced by the new satellite Yamal-601.

Yamal-series spacecraft made at Energia are a perfect example of implementation of advanced science-based 21st century space technologies.

The launch of Yamal-200 satellites took place on November 24, 2003 at 9 h 22 min Moscow Time. Launch vehicle Proton-K put the ascent unit into a parking orbit. Delivery of the stack of two spacecraft from the parking orbit to their target orbit was carried out by a Block DM-type upper stage (11861-01). After the spacecraft stack separated into SC-1 and SC-2 the spacecraft transferred from the target orbit into their respective orbital slots in the geostationary orbit autonomously. The SC systems health was monitored by a mission control center. The mass of SC-1 is 1360 kg, the mass of SC-2 is 1320 kg. The design life in orbit for the satellites is just above 12 years.
