radiogoniometern.
/ˌreɪdɪəʊˌɡəʊnɪˈɒmᵻtə/, U.S. /ˈˌreɪdioʊˌɡoʊniˈɑmədər/ An apparatus for determining the direction from which radio waves are coming without the need for a rotating aerial. Also called goniometer.A typical form consists essentially of a rotatable detector coil coupled to two fixed primary coils at right angles to each other, each of these coils being in turn connected to one of a pair of directional aerials also at right angles to each other.
