HC Deb 27 March 1928 vol 215 c959

asked the President of the Board of Trade whether his Department has yet instituted any experiments into wireless loop direction-finding system?


The rotating loop direction-finding system has been developed by the Air Ministry as an aid to air navigation. The system has been investigated by the Department of Scientific and Industrial Research, and preliminary trials have been carried out in connection with marine navigation. The Board of Trade have considered the results of this investigation and are now examining, in conjunction with the Air Ministry and the Trinity House, the question of establishing an experimental station of this type in a position where its utility, as an aid to shipping, can be fully explored. It is hoped to reach a decision on this question very shortly.
