Galaxy 15 Status Update

On 23 December, the power from the Galaxy 15 battery completely drained during its loss of earth lock and the Baseband Equipment (BBE) command unit reset, as it was designed to do. Shortly thereafter Galaxy 15 began accepting commands and Intelsat engineers began receiving telemetry in our Satellite Operations centre. We have placed Galaxy 15 in safe mode, and at this time, we are pleased to report it no longer poses any threat of satellite interference to either neighbouring satellites or customer services.

Intense Solar Storm Spins Satellite Out of Control

An adrift Intelsat satellite that stopped communicating with its ground controllers last month remains out of control and has begun moving eastward along the geostationary arc, raising the threat of interference with other satellites in its path, Intelsat and other industry officials said.
In what industry officials called an unprecedented event, Intelsat's Galaxy 15 communications satellite has remained fully "on," with its C-band telecommunications payload still functioning even as it has left its assigned orbital slot of 133 degrees west longitude 36,000 kilometres over the equator.
Galaxy 15 stopped responding to ground controllers on April 5. The satellite's manufacturer, Orbital Sciences Corp. of Virginia, has said an intense solar storm in early April may be to blame. It was launched into space in 2005.
