For six years both satellites simultaneously count with maximum accuracy the earth’s surface and thus the first global three-dimensional (3D) map is 90% ready. Missing only the massif of the Himalayas, some areas of Antarctica and some small islands in the Pacific Ocean. The latest fall but will record each hand, each and every iceberg palm. NASA has been cautious about the success of this project, but eventually brought out by the German Aerospace Center (DLR). The map has multiple uses. Natural and military.
Satellites TerrarSAR-X and TanDEM-X orbit around the earth at a distance of 514 kilometers
Moving in a spiral as the human DNA, a speed 28,000 km per hour, rotating 15 times around the Earth every day and with its help the recorded surface of our planet with a three-dimensional manner. The satellites accurately recorded 150 million cubic kilometers as if they were at a height of only 2 meters. The “eyes” saw them born an island and discovered hidden harvested forests.
As explains the director of High Frequency Technology Institute and radar systems of the German Center for Aerospace (DLR) Alberto Moreira, head of the space mission, two eyes are needed to see the world three-dimensional and two satellites to see the earth from space and to record a three-dimensional manner. Satellites, like the eyes should “see” the same place at the same time, in the case of radar waves. The two satellites are close together in just 120 meters. Not run parallel, but in a way that resembles the helix of human DNA. That’s why NASA considered that the operation will fail since it will conflict with each other. A satellite transmits each time its data, then both satellites receive the signals that are reflected from the surface of the earth and sending photos on earth in a special observation center Omperpfafenchofen Bavaria.
Nothing escapes the eye of the radar
As it still captures and moves on the surface of the earth. The data sent to earth is precious and of course there is controversy over their use. Whoever holds can accurately monitor climate change, to better design the construction of roads and military operations.
