SAR-Lupe
SAR-Lupe was Germany's first reconnaissance satellite system of Bundeswehr used for military purposes. The program started operation in 2008. Continuous operation of the system has ceased at least since 2020; individual SAR-Lupe satellites have been decommissioned or have already burned up in the atmosphere. It is being completely replaced by the SARah system.
The SAR-Lupe program consisted of five identical (770 kg) miniatur-satellites, developed by the German aeronautics company OHB-System, which were controlled by a ground station. A large data archive of images will be kept in a former Cold War bunker belonging to the Kommando Strategische Aufklärung (Strategic Reconnaissance Command) of the Bundeswehr. The total price of the satellites was over 250 million Euro.
SAR is an abbreviation for synthetic-aperture radar, and "Lupe" is German for magnifying glass.
