Been a subscriber now since January,love it!!! Just wondering, how does this whole thing work. I know the studios are in New York, but where is the uplink center ect. How does the one country station broadcast from Tenne. and not New York? I heard there are three satellites for the whole system, how does it work. Thanks....

Sirius Newbie question..........

Not all the shows originate in New York. Some shows on some channels are done at locations, e.g. Rock N Roll Hall of Fame, NASCAR Hall of Fame, etc.
The satellites are not stationary. They are in a Molniya orbit, looping over North America. One comes into range in part of the country as another moves out.
Doesn't Sirius have one geostationary bird like XM does? I know that they have the 2 of 3 circus of birds, but how do you tune in just the stations Sirius bird on your home antenna now? How do you know which way to aim it?
Thanks,
Thanks,

The antenna aiming doesn't have to be pinpoint, and the orbits take care of the rest (see link below). That said, here in the Mid-Atlantic, I do notice some spotty reception trouble for the brief periods when both the exiting and arriving satellite are low in the sky (there is a steep hillside along the edge of the major commuter highway around here that makes reception there troublesome at those times).

Holy crap, Sirius could easily service South America and the Pacific Ocean even better than North America if that orbit is correct in the diagram! Wow! I wonder why Mel doesn't target South America?

Actually, the orbit is at perigee over South America, so the sats are low in the sky for most of the continent, move a lot faster relative to a ground observer, and their signals likely don't overlap (big coverage gaps after one sat moves away and before another moves in). They are at apogee (high point of orbit) over North America, therefore higher in the sky and in line of sight over a wider area and for a longer period. I'm just guessing but I bet if you could use a Sirius receiver in South America, you might be able to tune in at best for only about an hour three times a day (and that would include a lot of reorienting the antenna!).

With only one Spanish-language music channel (offering East Coast, Caribbean-based music only) a couple of Spanish-language news (TV simulcast) and sports channels, and nothing at all in Portuguese, the language of South America's largest nation, Sirius XM barely offers anything for the Spanish-speaking population of the United States. I doubt South America is even on Mel's world map, let alone in his plans.
Good point; Mel's "world" doesn't go beyond NYC; I'm surprised he hasn't cancelled all country stations since there isn't any in NYC.
With the Hispanic population growth, I'm still surprised Melvin cancelled two Spanish music channels (one was actually decent - Auguilla XM92) - he really lacks insight to grown Sirius/XM beyond his horse blinders and Stern & Oprah.
I wish I had a seat on the board to replace him with someone with some imagination and future outlook.
