Confocal emitters (in Toran)

Fixed stations generating a hyperbolic pattern. The stations are in no way related or synchronized and transmit unmodulated carriers, the frequencies of which differ by a small amount.




Please note that this is the term as it stands in the original IALA Dictionary edition (1970-1989)
