PLATH History

While PLATH has its origins in nautical instruments in 1837, The PLATH Group of companies evolved from a radio navigation company that originated in 1950, led by Maximilian Wächtler, a pioneer in radiolocation and radio and remote intelligence – he held over 60 patents in this field. This eventually became PLATH GmbH and has more recently become the PLATH Group. Such is the influence of PLATH that training material written in the 1990’s are still used today by the German Bundeswehr’s electronic warfare section and are standard intelligence literature. The PLATH Group now holds over 200 patents in the COMINT and SIGINT sector.

PLATH‘s long history of COMINT innovation

PLATH‘s long history pre-dates COMINT with some of the foundational navigation technology that naturally progressed to its pioneering position in COMINT that started in the 1950s.
