We have a Garmin GPS II Plus and a small bluetooth-connected GPS
for our cellphone.

While new GPS satellite systems are going up now,
we want to know how long we can reasonably expect
our current GPS gear to operate,
ie, with the original GPS satellite system system.

TIA

The US periodically replaces older GPS satellites with newer and
improved ones. These then for all it matters take on the personality
of the one they are replacing. I think that the maximum number of
active satellites is 32.

The older GPS receivers will pick up the new satellites and the
receivers can continue to operate normally.

My GSP II+ is starting to get periodic partial failures of the screen.
That's likely to be the limiting factor...

Mike.

My 12XL also has display problems - but that is just a hardware
failure in my (and your) particular receiver that has nothing to do
with the vintage of the GPS system itself.
