Yamal Satellite Heads Back on Track

MOSCOW, December 12 (RIA Novosti) – A Russian Yamal-402 satellite used its own engines and fuel for the third time on Wednesday to continue a push to its planned geostationary orbit, following a partial launch failure last weekend, Russia’s Gazprom Space Systems (GSS) company said.

The maneuver is part of a four-step recovery plan developed by aerospace company Thales Alenia Space to get the satellite into its target orbit, after it suffered a premature separation from the upper stage of a Russian Proton-M carrier rocket after launch last Saturday.

“Yamal-402’s engines performed the maneuver following a cycle of commands issued by specialists from Thales Alenia Space,” a GSS spokesman said.

“The satellite is steadily approaching a designated point on its geostationary orbit,” the spokesman added.

The Yamal-402 satellite was built by Thales Alenia Space for GSS, the telecommunications arm of Russia’s energy giant Gazprom, to provide communication links over most of Russia, the CIS, Europe, the Middle East and Africa.

The satellite, equipped with 46 Ku-band transponders, was launched from the Baikonur space center in Kazakhstan on December 8 but separated from its upper stage four minutes prior to the designated time, due to an apparent glitch in the Briz-M booster. The failure was not the first for Briz, which has an imperfect reliability record.

Even if the four-stage recovery operation is successful, the service life of the satellite will be reduced from 15 to 11 years due to the unexpected use of some of its fuel reserves.

The Yamal-402 is the second telecoms satellite launched for the GSS this year. A Yamal-300K telecoms satellite, built by Russia’s Reshetnev space company, was successfully orbited on November 3. Its coverage extends to 95 percent of Russian territory.
