All the recent Echostar models with built-in positioners have an autosat feature, which I think goes some way ton what you want. YTh user "manually" locates 3 satellites and the receiver calculates all sats between and/or adjacent to them.
Actually, it's quite clearly advertised in the literature. Take a look at thier homepage or pop down to your local sat dealer and pick up a brochure.
yes, like virtually every receiver on the market, the ad3000ip has its share of bugs. But it's still an excellent machine.
See here for more info (including bugs and wish-lists, mainly in English)
