COOLING OF THE GERMAN EXPERIMENTAL SPACE SURVEILLANCE AND TRACKING RADAR
The German GESTRA “German Experimental Space Surveillance and Tracking Radar” is a novel and very powerful phased array radar system that scans the low-Earth orbit for space debris and can acquire the corresponding orbital data. The GESTRA system detects and maps orbiting objects such as satellites, space debris and other celestial bodies. The collected data is catalogued in Germany and is also available to other space organisations, such as NASA and ESA, if required.
On behalf of the Fraunhofer Institute for High Frequency Physics and Radar Technology (FHR) and the German Aerospace Center (DLR), we developed the complete cooling system for the GESTRA project and produced a large part of the cooling system. Due to the very high demands on the cooling technology, we developed a variety of new technologies and successfully used them for the first time in the course of the cooling of the GESTRA project.
Among other things, the system cools the radar processor, the radar power supplies and the transmit and receive modules within the radar system. Without this unique cooling, the operation of the phased array radar system with its large number of transmit and receive modules would not be possible.

We look forward to your project!
