What is the significance of SAR-Lupe spy satellite to Germany?

SAR-Lupe is the first spy satellite system in Germany, which is mainly used for military investigation. SAR is the abbreviation of SyntheticApertureRadar, while Lupe means magnifying glass in German. On December 19th, 26, the first SAR-Lupe spy satellite was launched into the sky via the Russian pugliese Tsk Space Launch Site. In the following year and a half, four other satellites were successfully launched one after another. By July 22nd, 28, the whole satellite system began to operate normally, and the ground radar receiving station of the system was located in Dover, gayles.

performance

the p>SAR-Lupe spy satellite system consists of five satellites each weighing 77kg. These five satellites operate in three low-earth orbits with a height of 5 kilometers. SAR (Synthetic Aperture Radar) can generate high-resolution pictures (the resolution is .7 meters), and it is not affected by the weather. No matter day, night or bad weather, SAR-Lupe spy satellites can take high-resolution pictures, even the models of cars moving on the ground. Moreover, SAR-Lupe spy satellites can also shoot wide-angle and close-range, and can shoot objects with different angles and smaller volumes.

communication range

there is an inter-satellite communication link between the five satellites of the p>SAR-Lupe spy satellite system. Therefore, if the German military needs to get the information of a certain area, the ground control station only needs to send the instruction to the nearest satellite, which will quickly transmit the instruction to the satellite that can shoot the information of the designated area. Therefore, the German Ministry of Defence can receive the image data from any area in the world within 1 hours.

strategic significance

the p>SAR-Lupe spy satellite system * * * costs 3 million euros and cooperates with the French Helios optical reconnaissance satellite, so at present, Germany and France * * * enjoy the information obtained by these two spy satellites. The SAR-Lupe spy satellite is of great strategic significance to Germany. Wolfgang Kuhn, a German vice admiral, said that the SAR-Lupe spy satellite made the military investigation in Germany and other countries at the same level, even at the leading level.
