“ZombieSat”: When Good Satellites Go Bad
Added by USGIF Category: Daily Intelligence Brief, General
What happens when good satellites go bad? They drift through space, joining the massive amounts of debris floating out there like a zombie, potentially threatening other functioning satellites. This could certainly be the case with the Galaxy 15 commercial satellite that recently lost contact with the ground, and is now being dubbed by engineers as being “zombiesat.” Experts believe that this defunct satellite will probably drift to one of two “gravity wells” that catch most out-of-control spacecraft. The more challenging issue is that Galaxy 15 could threaten nearby satellites because its communications package is still working, and it could interfere with working satellites, and even siphon off their signals. The word is that this is the first time a satellite event like this has occurred, and we don’t really know what ramifications that Galaxy 15 will have on the myriad of commercial and military satellites floating around in space. We assume only time will tell. Read more about “zombiesat” here.

If the transponders as still on, Galaxy 15 still has value for many years as an ad-hoc relay satellite for SNG trucks or other users that can track and fix their antennas accordingly. Galaxy 15 now even has a new pet name: “ZombieSat”.
