There are a huge number of ancient structures on Earth. Most of these structures are not located randomly on the planet. They can be combined into a single system based on geometric principles. The system is linked to the geographical parameters of the Earth and is based on several key objects that form the correct geometric framework. In this video, we will look at the relative location of only the key objects of the system that are known to almost everyone. This is an ancient navigation system for flights. Geometrically correct location of navigation objects makes it possible to transfer them together with the scanned terrain to a digital model of the globe and create a 3D map. Then, by comparing the terrain in any particular place on Earth with the digital model, you can determine your location and Orient yourself.
