Positioning based on space started in early 1960 and followed up by the United States and NASA. One of these early and very successful systems of positioning was the TRANSIT Satellite. Since its launch in 1967 for commercial purposes, this satellite has gained many applications in surveying and geodesy, especially in cases where the goal was to establish a vast network of stations in large areas and even on the entire Planet. TRANSIT Satellite system has been very useful for establishing new geocentric assumptions and for linking different data (assumptions) to a geocentric reference framework (i.e., It’s origin at the center of the Earth).
