Approval of Passiv-Radar-Systems (PARASOL) - dark nights, but emission-free
After month and years of development, tests and improvements the Dirkshof received the second and final approval from Deutsche Flugsicherung for its innovative concept of aviation waring system. The system is working without new emissions, it is using the existing airwaves from Radio and TV, like DVB-T, DAB plus or LTE. And therefor it doesn’t need a separate frequency – what is another big plus factor in the approval process.
