GPS World: USNO's Fountain: Time at 100 Trillionths of a Second

Hmmm... Homeslice? Is that a new derogatory term?

What does not work that way again?

Whom have I cited again? What hobbyist write-up? Remember you are
the ones who brought up these lousy applications that are mere

 

It sounds like you bought a cheap GPS receiver without additional

Sam is describing himself using a mirror. <shrug>

You've been arguing this idiocy since early 2005, and you are
STILLLLLL WRONGGGG.

 

That is doubtful. He hasn't enough electromagnetism
to make a mirror work. There IS the possibility
that "Alice" is operating the device for him.

Anderthal, are you spewing nonsense again? Have you forgotten that
you yourself disproved GR when you stated the motion of the earth is
distinguishable from that of a star, thereby violating the very
principle that GR was made for?

Your tail is so far between your legs that it has come around the back
and covered your eyes.

 

This could be true in some system other than the GPS. But it is not true
in the GPS. That's because the GPS consists of MORE than just the
satellites and the receivers, and because the actual GPS has
requirements OTHER than just permitting receivers to determine their
position and time. The GPS has a ground control segment whose clocks are
REQUIRED to remain in synch with the space segment's clocks, GPS time is
REQUIRED to remain within 1 us of UTC (modulo leap seconds), and the
space segment is REQUIRED to meet its requirements for a month without
updates or corrections from the ground segment.

There is no way for a receiver's determined time to remain within 1 us
of UTC for a month without the ground segment, unless the much larger GR
correction is applied to the satellite clocks.

Note there are a number of GPS applications that ignore
the positioning data and just use the time data, and rely on
it being with 1 us of UTC. Note also that the GPS is a MILITARY
system, with military requirements and engineering.

In short, you are NOT discussing the GPS, you are discussing some
figment of your imagination.

Guys, why are you wasting so much to answer to this not-funny,not-
educated, stupid troll???
The best way to handle him, is just to ignore him and all the stupid
things he write...
No waste of time, and maybe that when he'll not receive answer
anymore, he will get a real-life

 

Are you CrAzy, Strich--the relative velocity between on observer on
the rotating earth, hurtling around the sun, and a distant star is
measured routinely... and some measurement incorporate GTR!

 

The ring laser interferometer has a laser process that generates two
frequencies of laser light.
In every section of the ring laser cavity, the light propagates with
the same velocity in either direction. For the sake of simplicity,
assume that all emitted photons are emitted in a direction parallel to
the ring. (That is in fact a huge simplification, but it does not
affect the content of this exposition.) The atoms in the laser cavity,
represented as grey dots in the animation, have a thermal velocity,
and on average they have a velocity in counter-clockwise direction
along the ring. The molecules in the laser cavity can be seen as
resonators. A passing photon will stimulate emission of the excited
molecule only if the frequency of the passing photon exactly matches
the frequency of the photon that the molecule is ready to emit.
I understand this but in space as a ring passes through a
gravitational field circles become slightly oblong and stretched even
at non-relativistic speeds so I don’t trust their accuracy since the
circular paths of passing photons will stimulate the wrong emission of
the excited molecules causing the frequency of the passing photon not
to match exactly with the frequency of the photon that the molecule is
ready to emit.

 

There is no way for a receiver's determined time to remain within 1 us
of UTC for a month with or without the ground segment, unless
the much larger upload correction is applied to the satellite clocks.

In short, you are totally clueless and a lying shit, Roberts.

 

No need for the sun, moon and stars. We routinely measure relative
velocities of cars, baseballs, tennis balls, ping pong balls, bullets,
etc. What are you trying to argue anyway, that GR principle does not
apply?

GPS demystified:

http://electronicdesign.com/Articles/Index.cfm?ArticleID=15475

Almanac data is only 50 bits per second. This data is chipped by two
frequencies each creating its own broadband signal. One is 1.023MHz
with 1.57542GHz carrier, the other one is 10.23MHz with 1.2276GHz
carrier. That is all.

To acquire one’s position, you need to find the following unknows:

** Your position on altitude
** Your position on longitude
** Your position on latitude
** Your time measured in satellite time

Four satellites will send you information on their satellite time and
positions. In doing so, you get a set of four equations. Solving
these four equations, you will get the four unknowns and that will pin-

Either you are claiming mysticism or know something that only the
military knows. In this case, I still call your bluff. As a
physicist working for Lucent, the odds are against you to be involved
with top-secret GPS development. Therefore, you to be demystified:

** FAITH IS THEORY
** MYSTICISM IS WISDOM
** IGNORANCE IS KNOWLEDGE
** PLAGIARISM IS CREATIVITY
** CONJECTURE IS REALITY
** BELIEVING IS LEARNING
** LYING IS TEACHING

It appears that Sam Wormley's Pappy
taught him to lie,
or else he has a serious reading comprehension problem.

As can be seen, in many of my posts,
I have described the affects that
the Galileo Effect (Gravity-acceleration)
the Doppler Effect (Velocity),
and the Hubble Effect (Distance)
have on oscillators,
and upon the perceptions of observers.

"The evidence is in Potter's posting record."
not in Sam Wormley's parroting of lies, over and over.

As my Pappy used to say:

"Don't believe lies and hearsay."

"If you want good information
get it from the horse's mouth,
not from a horse's ass."

Here comes the chronic liar to lend support with no literature

Potter, GTR has directly contributed to a $30B+ GPS industry,
benefiting people all over the world. Aviation, shipping, asset
management, survey, mining, agriculture, time dissemination,
communications networks... and on and on!

Bluster on, Potter, bluster some more! Froth at the mouth! Whatever!
