Galaxy 15 is one of the satellites the FAA uses for rebroadcast of WAAS correction data. It's also not responding to commands and drifting towards other satellites.

The two satellites pose little risk of crashing into each other, but Galaxy 15's C-band communications package is stuck on and could siphon away signals meant for other spacecraft if it strays too close. The Intelsat-operated Galaxy 15 went rogue on April 5, apparently due to a solar storm, its Virginia-based builder Orbital Sciences Corp., has said.
