The Decca’s Original Purpose

January 23rd, 2014 | Posted by Gavin, M1BXF in General

The cottage we are staying in for the 2014 DX’Pedition, The Decca, is so named for its original purpose.

The Decca Navigator System was a hyperbolic radio navigation system which allowed ships and aircraft to determine their position by receiving radio signals from fixed navigational beacons. The system used low frequencies from 70 to 129 kHz. It was first deployed by theRoyal Navy during World War II when the Allied forces needed a system which could be used to achieve accurate landings. After the war it was extensively developed around the UK and later used in many areas around the world.
