GPS is stuck with a set of satellites - how to remove them from memory?

[tichi]

I seem to know why SOMETIMES it takes forever
to get a satellite lock with GPS.
(I learn that many users experience this problem, including those on Bell, and including those with NSFSAN's ROM 1.10, like me).

After you get a successful lock, a few satellite numbers (like those 4,2,9,12,22 etc, that you see in GPSViewer) are stored
somewhere on the phone.

Next, when after some time (overnight, let's say), you try to get another lock, the OLD satellites moved, they are not available anymore,
but the phone tries to use them anyway, WITHOUT UPDATING...

(my highly subjective perception after some observations is that if there's is one-two OLD satellites still avaialble, it may be still OK for the phone to find the new ones, but if NONE of the old satellites are available,
the phone is stuck, and may sit forever looking for them..

what helps is a SOFT-RESET (which clears some memory, I suppose) - after that - ther's a A FAST (10ns) LOCK, with NEW SET OF SATELLITES (e.g .13. 15. 3. 7 etc )..

so my question is WHERE those satellite are stored, and how to clean them without doing a soft-reset?

("HTC GPS Tool" that has some "clear-memory" button does not seems to help, maybe because it is for another phone model?)

EXPERTS, PLEAAASE!
