Yamal-101 (Russian: Ямал-101) was a geostationary communications satellite operated by Gazprom Space Systems and built by RSC Energia.[1] It was, along with Yamal-102 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-102, 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] But a failure in the electrical system at solar panel deployment meant that it was lost right after the successful launch.[9][1]

Rename of Yamal-102[]

After Yamal-101 failure, 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] Insurance paid US$50 million for the failure.[11]
