Q. WHAT WAS THE SEVER SYSTEM?

A. In the 1970's and 1980's (before satelite communication introduction) Russian military bases located at low-populated far away places had to communicate somehow. It was hardly possible to connect them by radio communication because this required too much effort. Besides radiotraffic was not secure, could be intercepted.and the distances combined with the weather conditions often made them unreliable.

So Russian army implemented networks of high power stations that fired their messages to the ionosphere (the SEVER system).
There the message was reflected and bounced back to the earth surface… right to another station.
By connecting those stations in a relay chain they could communicate instantly through all 10000 mile wide Russian territory!
Another nice side effect was the fact that these troposcattter communications could not be jammed or intercepted!

However after the SATtelite COMmuications came into play most of the stations became obsolete and have been closed or converted to SATCOM links.
