I'm sorry you have bit into this complete bit of marketing. That's all it is. Period.
No GPS on the market (and I've used consumer, military, commercial navigation, etc) can "know" where to look in the sky for the GPS satellites, nor would you want them to.
Every GPS has an omnidirectional antenna, meaning the antenna "listens" in all directions, equally.
Since the GPS is listening to multiple satellites at a time, with a non-directional antenna the idea that the GPS is "looking" for a special area of the sky is complete BS.
How your GPS works is it each Satellite sends out time mark signals, the GPS measures the difference in arrival time for the time signals. and computes your location based on these signal.
Thank you for that information. It is interesting to learn about areas that I'm not qualified to speak about.
Thanks,
