Then you can use 'c' in that frame as well. <br /> <br /> Sagnac measured c +/- v in the rotor frame, also. Another contradiction. <br /><br />Tom B:..... Neil Ashby describes how the required GPS clock synchronization could not be achieved until the corrected synthesizer was turned on (see General Relativity in the Global Positioning System by Neil Ashby). <br /><br /> Ashby: "The atomic clock was first operated for about 20 days to measure its clock rate before turning on the synthesizer. The frequency measured during that interval was 442 * 10^12 parts in faster than clocks on the ground; if left uncorrected this would have resulted in timing errors of about 38,000 nanoseconds per day.".....<br /> <br /> This shift could be due to the Sagnac effect alone, depending on the component of radio signals in the E-W direction. <br /> <br />Tom B:Today, the relativistic correction is described in the GPS specifications. ......<br /> <br /> "One of the characteristics of clock behavior clearly evident in GPS is that all clocks in the earth-centered inertial (ECI) frame at sea level run at the same rate. On the equator they should run slow according to SRT due to its speed in the ECI frame. However, on the equator they should run fast according to GRT due to the spin-induced equatorial bulge which causes the clock to be higher in the earth's gravitational potential. These two effects, explained by two disjoint theories, are of exactly equal magnitude but opposite sign".<br /> <br /> "SRT and GRT theories sometimes exhibit clock effects of equal magnitude which cancel and sometimes exhibit clock effects of equal magnitude which are additive. This cannot be coincidence, yet there is nothing within the two disjoint relativity theories to suggest an underlying mechanism. Since clock effects are a function of velocity squared (kinetic energy) and gravitational potential energy, it would seem that the common factor is related to the energy of the particle. But SRT treats kinetic energy as relative and GRT treats gravitation as a geometric effect of an orbiting body following a force-free trajectory completely independent of energy considerations. SRT/GRT has no valid explanation for this phenomenon. Thus, both Einstein theories are invalid"<br /> <br /> <br />Tom B:So I ask the question, could Physical Geocentrists have built a working GPS system?<br /><br /> The above quotes are from GPS consultant Ron Hatch, who did help build a working GPS system....Robert Bhttps://www.blogger.com/profile/09437016927399027310noreply@blogger.comtag:blogger.com,1999:blog-2361412992308994774.post-76299505673074034972010-11-10T14:37:25.160-05:002010-11-10T14:37:25.160-05:00Tom B: .....

Shapiro's talk titled OBSERVATIONAL TESTS OF RELATIVITY gave the illusion that the Venus radar data was consistent with Einstein's general relativity theory. ...in the comment session that followed, he admitted that all his calculations were based on a constant speed of light c (the wave in ether model), and he had not tested c+v (the particle model). ... He admitted that the published radar analysis showed very large impossible variations in the calculated value of the astronomical unit (the mean distance between the earth and the sun), that were far larger than their maximum estimate of all possible errors. ......The variations in the calculated value of the astronomical unit are what one would expect to find if the speed of light was c+v, and the [Shapiro] calculations were based on c.<br /> http://bourabai.kz/wallace/farce06.htm<br /><br />Tom B: In addition, there are currently at least two satellite instruments flying in space, moving relative to the Earth, AND to the object they're imaging, where the optical configuration used is similar to the Michelson-Morley experiment. ....<br /><br /> 1- Relativity is inconsistent in its 2 premises which state that physical laws are the same for the states of systems in constant relative motion and physical laws are the same for photons in constant absolute motion.<br /> Inconsistent (internally contradictory) theories are unscientific; they can prove anything is true and false. <br /> 2- What are the names/references for the 2 Doppler-effect satellites?<br /> <br /><br />Tom B:As high-bandwidth transmissions become common in space, we will have to include the relativistic effects there as well to keep precise timing. Physics Today: Time dilation seen at just 10 m/s.<br /><br /> If there is a relativistic time dilation how are the same predictions of other theories eliminated? How is time dilation necessary and sufficient to explain the effect? <br /><br />Tom B:The GPS system uses several different coordinate systems, including an inertial system with an orientation fixed to the distant stars. Computations transform to a geocentric system when needed to compute locations physically on the Earth. <br /><br /> 1. These several different coordinate systems..... which ones are not geocentric(GC)? <br /> 2. GPS also uses ECEF(the geocentric system) as a valid frame of reference. The ECI system is just a rotation of ECEF westward with period of a sidereal day. <br /> 3. How about an airplane or satellite, Tom? They do not have locations on the Earth, but a GC system is used to locate them...<br /> <br />Tom B:According to relativity, provided you do ALL your calculations in a given frame, you can always use 'c' as the speed of light in that frame.<br /><br /> 1. If light speed is an absolute constant, why the restriction to one frame? Isn't light speed c in every frame? <br /> 2. Sagnac used the ECEF frame to measure light speed and obtained c +/- v , where v is the rim speed of a nearby rotor. Ruyong Wang found the same for linear motion of a light beam in the ECEF. If Sagnac used c, his calculations would always be wrong.Robert Bhttps://www.blogger.com/profile/09437016927399027310noreply@blogger.com
