THE USE OF COMPOSITE SIGNALS AT VERY LOW RADIO FREQUENCIES.

When the time of arrival of a VLF transmission is measured at two frequencies the two components can be combined to form a 'composite signal.' This signal, when the transmission is chiefly determined by a single mode of propagation, has advantages in stability and predictability as compare...
