Copy to Rob, as I know he is interested. Neville, I cannot remember if you answered my objection to your view, that the geostationary satellite does not exist because the electronics would not work in those regions of space. Perhaps I need to clarify what I said with more detail which came to mind this last night. This is an important point as quite a lot of your other controversial ideas re space research hinges upon it, re the honesty of NASA Moon shots etc. I do not believe that such satellites in any way constitute evidence supporting the heliocentric position, which tries to maintain that such satellites would fall back to earth if they were immobile with a immobile earth, but that for another post..... I firmly believe that there must be a satellite relay in orbit approximately 35,800K above the earth, for the following reason/proof. For the non Radio technical person I have tried to keep it simple. A. The Ultra High Frequencies used of microwave lengths, cannot project over the horizon. They are strictly line of sight. They can be and are extrremely focussed as a beam. with a parabolic antenna, following patterns almost identical to a flashlight for transmission.(and reception) This antenna is really a radio telescope, the dish analogous to the mirror for reception. It can be focussed for wide or narrow beam. B. With such a receiving antenna connected to a signal strength meter, it is possible to measure and project a graphical representation of the variation of signal strength as a curve, from null signal to peak and back to null as tha antenna is moved through azmith and elevation across the section of sky being scanned.By taking the mean of these readings it is possible to establish a very accurate point in the sky as one line to the position of the source of the transmission. C. Now If we have say three such receiving antennae all aimed at the exact same transmitting source, from widely spaced locations on the earth within the beam, (called footprint) of the transmitting antenna, surely you can see from the geometry that the azmith/elevation angles triangulating to a known measured base on the ground, can very accurately prove the transmitter to be where it is at nearly 36,000kilometers above the earth. Planning as I am to buy and install a dish to receive free to air sat transmission, I have obtained the necessary angles of elevation and azmith nececessary to achieve quick and accurate installation for our entire region/state. They are all consistent with just one spot/point in the sky, and any deviation from this spot will fail to receive a signal..I am sure the figures are available for every part of the world on the internet, for every satellite, and if you wanted you could do the geometrical calculations yourself, but just a glance and you would see there being no need to do that.
