I never understood how the PPP (Public Private Partnership) model was ever
going to work on Galileo. The recent drop out of private funding proves my
point. Unfortunately the EU (another white elephant or whale!) will continue
to pump taxpayers hard earned money into this system to save face.
In my view, using EU money to build the GALILEO system is a good idea!
Using EU funds to subsidice(?) european agriculture is a MUCH worse idea!

Hi Björn,
I agree with the second comment also!!

Metastability was mentioned again recently - I think I read some
messages earlier this year, but can't remember if they were current, or
in the archive, and can't now quickly find them. I think it has to do
with latches getting into an undeterminable state when asynchronous
Hi:
While trying to learn about pendulum barometric compensation I came across a
Google book that's very interesting. Has minutes of the R.A.S. and other
meetings at the time just after Greenwich was selected to be the keeper of
time. Here is a link to it:
You need to have a two stage register, allowing one clock period
for the first stage to come out of metastability. This of course
delays the signal to be synchronized by a clock period. In an
attempt to get around this delay, you sometimes see a series of
registers in cascade clocked at slightly
Metastability is simple after you get it. Lots of people, including some who
should know better get it wrong.
The best real world analogy that I know of is rolling a ball over a bump. If
the ball has lots of energy, it goes over over the bump and down the other
side. If it doesn't have

Navman for some time made a functional clone of the Motorola 8-ch
receiver, and although it is a 12-ch receiver, I believe it talks the
8-ch language used by the GPS receiver in the Z3801A. This was Navman's
model Jupiter T. It was the same size and shape, and had the same
connectors, as

Yup. The delay is unavoidable. The only thing you can do is trade off delay
vs MTBF.

Thank you both, and particularly Hal, for your explanations - I think
I get it now. It's great to have you experts online!
Thanks again,
