GE 14


Also called AMC 14, USAT-S1

General


Designation 32708 / 08011A
Launch date 14 Mar 2008
Country of origin United States
Mission Telecommunications
Geostationary orbit 34.5°E, highly inclined
Launch vehicle Proton #336

Proposed BSS satellite, part of AMERICOM2Home. The licence was held by SES Satellites (Gibraltar) Ltd. The construction launch and insurance cost $325 million. The satellite was insured for $150 million. The entire capacity had been booked by Echostar. Should have tested from 56.5°W and operated from 61.5°W.

After the launch failure and the declaration of total loss, the satellite was sold to the US DoD for $150 million. Slow orbit raising started afterwards. In Jan 2009, the satellite finally arrived in GEO, but with a highly inclined orbit.
