As can be seen Sam Wormley confuses clocks with oscillators,

continually controls the oscillators and clocks on the GPS satellites.
I suggest that Sammy do a little research on why
af0, af1 and "Time of Applicability" data
are transmitted to GPS receivers.
Note that af0 has the dimension of seconds,
and that af1 has the dimension of seconds per seconds.
The af0 (Seconds) data tells GPS receivers how much
the clock on a particular satellite
differs from the master system time,
and af1 data (Seconds per second) tells GPS receivers how much
the oscillator on a particular satellite
is drifting with respect to the master system oscillator.
Potter, try not to be so stoooopid.
See: http://www.navcen.uscg.gov/gps/geninfo/IS-GPS-200D.pdf, pg 88
The SV PRN code phase offset is given by
Î"tsv = af0 + af1(t - toc) + af2(t - toc)2 + Î"tr
where
af0, af1 and af2 are the polynomial coefficients given in subframe 1,
toc is the clock data reference time in seconds (reference paragraph
20.3.4.5), and Î"tr is the relativistic correction term (seconds) which
is given by Î"tr = F e A^0.5 sin Ek.
Look it up: http://www.navcen.uscg.gov/gps/geninfo/IS-GPS-200D.pdf
Sammy, the so-called relativistic correction term
has to do with corrections for the eccentricity of the satellites orbits,
the shape of the Earth, etc.
and as can be seen from the publication you quoted::
"Since these coefficients do not include corrections for relativistic effects,
the user's equipment must determine the requisite relativistic correction."
I suggest that you do some research on the ACTUAL software
used in GPS receivers, and see if you can come up with
a routine or two that demonstrates these
so-called relativistic corrections.
I might point out that England sent ships all over the world
hundreds of years ago with standard oscillators (Pendulums),
to count the swings from sunrise to sunrise,
and Newton used this data to compute
tides all over the world,
the Moon's affect on the tides,
and the shape of the Earth.
To my knowledge,
Newton didn't even know about Relativity,
General or Special.
