"Is there any such evidence for the Earth’s daily rotation? Let’s look at Pioneer 10 and 11, two spacecraft that were launched in 1972 and 1973 respectively, to study the asteroid belt, Jupiter and Saturn. After completing their mission they continued on their trajectory out of the solar system at well above escape velocity. Pioneer 1034 remained in contact with earth stations until 2003 when it was some 12 billion kilometres away. You will remember that the Sun has by far the biggest gravitational field in the solar system and for that reason both Pioneers were slowed down by the Sun’s gravity as they flew away from the solar system. However measurements of the spacecraft position and speed indicated that both Pioneers were slowing down more than the models predicted and for several years this effect, known as the Pioneer anomaly, was a mystery. All we need to know about the anomaly is a) that it was tiny (~10-10 ms-2 - a hundred billionth of the acceleration due to gravity at the Earth’s surface) and b) that it has been explained with perfectly conventional physics35. What is relevant to us is the fact that the anomaly was so small and therefore, in order to measure it, physicists needed to know the position (range and direction) of the satellites with extreme precision. These measurements are made by Doppler measurements and timing of radio signals sent to the satellites and returned to Earth ground stations. There is a daily modulation of the Doppler signals caused by the fact that Earth’s rotation causes a daily change in the relative velocity between the spacecraft and the Earth which physicists must correct for. In fact this daily Doppler modulation is used to measure the direction of the spacecraft from the Earth (its amplitude gives declination and its phase gives right ascension)."


Is there a yearly one?

That is about the question I asked here:

Has Cassini-Huygens spacecraft earth flyby in 1999 disproven geocentrism

"If earth is stationary, it ought to remain at the origo of the flight of a rocket (the spiral movement of which is explained by influence of daily movement of universe around earth). If it be moving around sun, it ought to return to it only once a year."


In other words, have the spacecraft been observed as zigzagging by parallactic observation from an earth rotating around the sun?

Of course. See ref 36 in the paper.

Best regards

  • a) Can you identify this reference?
  • b) Is the paper in question available in the libraries of Paris (especially excepting Georges Pompidou)?

  • PS, c) is it available online?
