Improved Safety in Space: The GESTRA radar system

Deutsche Version:    • Mehr Sicherheit im Weltraum: Weltraum...   Media Cleanfeed: https://vimeo.com/427413811/4de603f451 ------------------------------------------- GESTRA (German Experimental Space Surveillance and Tracking Radar) Several thousand satellites, spacecraft and other objects are travelling in Earth orbit. However, this region also contains hundreds of thousands of pieces of space debris. In total, this amounts to approximately 8000 tonnes of material. The majority of the debris – approximately 75 percent – is at altitudes of between 200 and 2000 kilometres, referred to as 'low-Earth orbit' (LEO). There is therefore a high risk of collisions with space infrastructure. The International Space Station (ISS), which is orbiting Earth at an altitude of approximately 400 kilometres, is affected by this. A constant supply of reliable data on the situation in space is required in order to prevent collisions. This has created the need for radar systems such as GESTRA. https://www.dlr.de/content/en/article...
