Basically it all boils down to the 15 year design life of the satellite . It was launched in 2004. When the fuel for the geo-positioning thrusters runs out, they will either use the remaining fuel to push it up further and out of the way or slow it down and let it burn up on reentry. Either way sometime this fall or winter our signal will go pfffft. Gone. As I understand it. It was good while it lasted. Hope I'm wrong but .......
