Satellite laser ranging (SLR) is a useful technique to determine the geocentric position
of the retroreflector equipped satellite using laser pulses back to the transmitting site.
As our discussion above revealed, the condemnation of Galileo at his 1633 trial was not that science is evil and religion is good: the issue was that he had unintentionally (intentionally?) promoted the heliocentric position over and above the geocentric position
, in defiance of the Church's 1616 decree.
The geocentric position
of the computation point in Eq.
The Catholic Church finally recanted its geocentric position
Gallistell (1990) suggested that maps are constructed by the egocentric position vector of landmarks being rotated by the geocentric orientation of the animal, and this rotated vector being added to the animal's geocentric position
vector (see Figure 7).
3) Vector of the star geocentric position is calculated with consideration of parallax [pi]:
Corrected geocentric position of the star is expressed by the equation (Krynski and Sekowski, 2007):
Two or more repeated observing campaigns have to be analysed in a common reference frame to obtain mean geocentric position
and velocity of the monitored point.
Detailed knowledge of local geoid surface recently has become increasingly important in order to fully use the potential of accurate geocentric positions
