Space-Based Positioning was begun and followed up since 1960 by the U.S. government and NASA. One of these early and highly successful systems of positioning was the Transit satellte. This satellite, since its launch in 1967 for commercial aims, has also gained applications in surveying and geodesy, especially where the goal was to establish a vast network of stations in large areas and even whole the earth. The Transit Satellite system has been of great use in establishment of new geocentric assumptions and also for connecting various data (assumptions) of place to a geocentric reference framework (center of earth).
