I saw on orbitcast a new sat is launching for sirius. I am real pumped about this, because finally it will be stationary, and I might be able to get a consistant signal at my house. Does anyone know when this is launching? Also when will it be useable? Oh and finally what direction will I have to aim?

no I don't think so. From what I've read it doesn't seem like that will be the case. ANy idea when it launches?

The best I've been able to figure is that they'll turn off one of the elliptical sats so that only one of those three birds is hot at any given time. I think the two things gained would be a little more stability to the signal, as well as possibly a longer life span for the elliptical satellites since they will not be used so much. The other satellite will be the geostationary one at a relatively low orbit over the equator. Obviously the ground repeaters would remain untouched.

I have been hearing that they will not have to do this. These can broadcast at the same time. Thats the theory anyways.

The geostationary sat will be in a higher orbit. To maitain the grostationary position, it needs to be way up -- same distance as the XM ones.

June 29th launch. Probably not online for at least 3-6 months after that.

3 to 6?
What, do they have their own CS team trying to figure out how to turn it on?

"Thank you for calling Sirius XM Customer Service, how may I help you?"
"I'm sorry Mel, your credit card was declined, if you call us back with a different card, we can restore your service in 3 to 6 months."
"Thank you for calling Sirius, the best radio in radio."

They have asked for FCC approval for launch and broadcasting on a test frequency. I think XM took about 3 months for XM-4 for it to pass its internal tests and be ready for broadcast. I assumed it would be the same.

I believe Mels credit card has been shredded some time ago.

Actually, IIRC, the apogee of the elliptical sats is higher than that of a geostationary satellite (the perigee is lower).
