Telefunken RACOMS was commissioned in 2016 to modernize the Saterland-Ramsloh naval radio transmitter (NATO VLF/MSK Rhauderfehn naval radio transmitter) to ensure modern management capability and consistent communication between the German submarine fleet and submarines of NATO partners. The implementation of the project by Telefunken RACOMS included the integration of modern semiconductor and information technology. The implementation also included training and logistical services.
After almost three years of work, Telefunken RACOMS handed the naval radio transmitter back to the navy in a regenerated condition. The Saterland-Ramsloh naval radio transmission station was the first of several VLF systems in the NATO network to be converted from VLF MSK transmitters based on tube technology to modern VLF MSK transmitters based on semiconductor technology. With this regeneration, an improvement in the signal quality could be achieved operationally. These activities were carried out under great time pressure, as there was a broadcast obligation in the NATO network.
Due to further extensive technical innovations on the control, extensive training services for the operating and maintenance personnel were also necessary.
With eight 352.8 m high transmission masts, the naval radio transmission station in East Friesland is one of the tallest buildings in Germany. The masts belong to two identical transmission systems, each with 100 kW transmission power per mast. Using the terrain (flat moor), the longest wave transmitter reaches submarines all over the world in water depths of up to 30 meters. The plant has been in operation since 1982. After the modernization, the operation is to be continued for another twenty years.
