Re: Simple experiments that conclusively disprove General Relativity

As can be seen Sam Wormley confuses clocks with oscillators, and seems to think that the GPS ground control 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
Δtsv = af0 + af1(t - toc) + af2(t - toc)2 + Δtr

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 Δtr is the relativistic correction term (seconds) which
is given by Δtr = F e A^0.5 sin Ek.
