This electronic reconnaissance station will be currently modernized. The previous and old system OMEGA is replaced by a new one. Not all of the visible antennas are still in operation and they will be removed sometime. The inside of this facility is top secret. The data is transmitted via fiber optic cable to Dübendorf. Often, a hiker will have wondered about the meaning of this station with the many antennas. Nevertheless, there are almost no pictures of this station on the Internet. (classified / no geotags).
