Stupid Attorney taling about GPS's

As far as Clinton goes, it's ancient history.

And you've forgiven Nixon, right?

Clinton, like Nixon, was among the worst blots ever to stain the
American presidency.

Far from "getting over it" or "moving on," I would say: "Those who do
not study history are condemned to repeat it."

I told this to my flight instructor, formerly an engineer. He said:
"That would be true only if Doppler callibrated the instrument."

I looked at the link you posted. It seems to be a summary of what is
intended to be presented at a seminar, with no associated evidence. It is
also not clear as to what Shaojun's definition of "inadequate" is.

It is not clear to me what method of integrity monitoring is going on in
the British airspace to which Shaojun refers, but it seems to be
unaugmented RAIM.

The summary indicates that his study "route" was London to New York. But
my understanding is that trans-oceanic flights have to have multiple
navigation systems, only one of which can be GPS.

Yup, and there is the 60mph bank, where every time the radar gun is at a
certain spot the bank registers at 60 mph... microwave motion detector at
the bank leaking radiation that mixes with the gun's frequency to produce
the spoofed reading
Oh, the officer will tell you that can't be... Ask him, what do you think
that the ECM box on an F 14/15/16/18/22/117 fighter does when an enemy fire
control radar tries to lock on...

That's a preposterous analogy, for a couple of reasons:

1) How many off-topic posts do you see on this newsgroup spontaneously
complaining about Nixon? I can't think of any.

2) Nixon slaughtered hundreds of thousands of South Vietnamese because they
had the temerity to defend themselves against a US invasion, as they had
done previously against the French and the Japanese. He subverted the US
constitution by using federal agencies to commit crimes against his
political opponents. He resigned the presidency in the face of imminent
overwhelming votes for impeachment and conviction. He would have gone to
prison (as did 25 members of his administration, including four cabinet
members), had he not been preemptively pardoned by his own former vice
president.

Far from "getting over it" or "moving on," I would say: "Those who do
not study history are condemned to repeat it."

Good principle, preposterous instantiation. You think it's important for
people to continue to complain to an aviation newsgroup about Clinton's sex
scandal in order to protect the Republic from the possibility that another
president will get a blow job and lie about it?

Our system of lifetime professional politicians attracts those with huge
egos and a burning desire to forego gainful employment.. The public feed
trough attracts these types like moths to a burning flame... It will only
end if we 'ever' put strict term limits on every elected position above dog
catcher..

And with term limits the populace will vote in the same characters with
different names.

Until the authority to spread money and favors (an authority they never
really had) is revoked, expect more of the same regardless of who is in
power or how many terms they (self)served.

I was never a Beavis and Butthead fan, but the other day I caught a few minutes
of the movie while flipping through the channels. They arrive at the Capitol and
make a PA announcement that they are looking for a girl with big boobs. The
entire house chamber then starts emitting the "heh heh heh" laugh.

Go say that in sci.geo.satellite-nav and see what happens.



Probably not a bad number.

Only if the usual caveats are added; i.e. 95% of the time and assuming

the

receiver has good reception conditions. Any attorney trying to

discredit

GPS evidence will naturally focus on the 5% of the time when the

position

could be off by more than the nominal accuracy and on obstructions,
multi-path reflections, RFI, etc. that can degrade performance,
particularly in a covert installation where the antenna is unlikely to

be

optimally placed for good reception.


False.

The convergence of the GPS Jacobian does not occur for the conditions

you

describe. One of the major advantages of GPS over current ground based
navigation is the difficulty of spoofing the system.


I suggest you read your "GPS World" issues some more. Improvement of
integrity monitoring was one of the main reasons for requiring

augmentation

of GPS.


False.

The failure to monitor the integrity of the WAAS signal is why the test
bit
remained set until recently. The integrity issues were WAAS integrity
issues with no relevence to GPS.

Unaugmented GPS has insufficient integrity monitoring.

See the CNX-80.

What is clear is that Peter has a tad more ego than knowledge.
