Yamal-102 (Russian: Ямал-102) was a geostationary communications satellite operated by Gazkom and built by RSC Energia.[1] It was, along with Yamal-101 the first communications satellite of the Yamal programme and the first iteration of the USP Bus.[2][3] It was a 1,360 kg (3,000 lb) satellite with 2200 watts of power (1300 watts available for the payload) on an unpressurized bus.[4] It had eight SPT-70 electric thrusters by OKB Fakel for station keeping.[5] Its payload was 12 C-band equivalent transponders supplied by Space Systems/Loral.[6]

History

It was launched along Yamal-101 on 6 September 1999 at 16:36:00 UTC from Baikonur Site 81/23 by a Proton-K / Blok DM-2M directly to geostationary orbit.[7][8] While its twin Yamal-101 failed, Yamal-102 successfully deployed and was commissioned into service.[1][9] On 9 August 2010, it was decommissioned and sent to a graveyard orbit. The satellite lasted 11 years and 2 months, a bit short of the design life of 12 years.[4][7]

Rename to Yamal-101

Right after solar panel deployment Yamal-101 failed irreparably. Thus, Gazprom Space Systems registered Yamal-102 as Yamal-101. This has caused significant confusion but the records are clear that the satellite that failed was, in fact, the original Yamal-101.[9][10]
