A system operating in the region of 2 MHz and providing a groundwave range of approximately 700-900 miles over sea water.
The time difference is measured by comparing pulse envelopes.
Greater range is obtained with reduced positional accuracy by employing skywave signals at maximum distances of approximately 1400 miles.
The occupied bandwidth is 35 kHz.
Please note that this is the term as it stands in the original IALA Dictionary edition (1970-1989)
