Most 'powerful' receiver?

Hi,

What is the most 'powerful' GPS receiver on the market? By 'powerful' I
mean the one that will pick up GPS signals when the others may not.
Ideally, it would have a CF card connected via wires so that the receiver
could be placed in the best spot, but Bluetooth would be OK too. Which is
the best GPS receiver that is 'wired' to the CF slot etc?

BTW: I have been using this 16-channel one and it works well, but apparently
not well enough:

Look out for ones with Srif Star III chipsets.

Hilton, you should understand that there are GPS signals... and there
are multipath reflections of GPS signals. Increasing sensitivity is not
necessarily an advantage.

Mark,

I have a Srif Star III receiver now, it is definitely better than the older
one I have from Dell.

Do you know of a receiver that:
1. uses that chipset (or better if such a thing exists), and
2. connects directly to the PPC; e.g. CF card, and
3. connects via a cable/wire so that the receiver can be placed (somewhat)
remotely; within 2-3 feet or so?

Thanks again,

Hilton

Especially indoors where most any signal has bounced around a bit.
I guess the lack of precise accuracy through multipath DOP to know where
in the building you really are isn't so bad as long as you have an idea
where the building itself is.

Interesting. Are there any plans to put up more powerful satellites that
will get GPS signals through trees, buildings etc? Sure there are some
places that GPS signals will never go, but not losing GPS signals while
driving Hwy 17 (Bay Area) would be good.

Thanks,

Hilton

My vehicle combines INS with GPS... a very good answer to signal
obstruction in places like the Bay Area.

Sam,

Wow, INS? Only heard of that in a car? Is there a portable device? URL?

Also, how much does an external antenna help? I just ordered one for $20 -
hopefully it is compatible with the Asus A636 (Suprisingly I couldn't find
one from Asus). I'm assume that it is better because it is larger and the
manufacturers try keep the Bluetooth devices small which is a Catch-22?
I'll report back what my results are and thanks again for all the replies.
