The previous papers in this series contain the locations of models of the planets of the solar system from Mercury to Jupiter, all of which have been derived from precise astronomical data. The model of Saturn, the next in the series, has yet to be identified.

In this paper I show that a model of Saturn is located in Sudan in north Africa and show that the distance between the models of Jupiter and Saturn is that of the relative range of the planets at the 2729 BCE winter solstice. The geodesic line that connects the two planet models is also shown to pass through the center of the model of the planet Mars thereby interconnecting the geometric features of the solar system model.

The instantaneous aphelion and perihelion distance at the winter solstice are then shown to also have been included in the model of Saturn and a second model of the planet is identified using these values on Easter Island in the Pacific ocean. The astronomical alignment of the planet model at Easter island is shown to be perpendicular to the airport runway and a third model of Saturn is identified in Athens which also uses the local airport's runway end point GPS coordinates as the essential part of the geodetic alignment.

Finally, at the end of the system at the Acropolis in Athens, the geometric geodesic line system terminates at the location of the model of Mercury thereby fully closing off the surveying system used within the whole solar system model's construction.
