In radio reconnaissance networks, the information items coming in from the various direction-finding stations (ST1, ST2, ST3) must be evaluated by an operator in the central direction-finding station in order to locate a radiation source on which a bearing has been taken. To enable the operator to be able to carry out this evaluation rapidly and reliably with the aid of a map and a drawing device, it is proposed to provide as drawing device a processor-controlled video device (VG) with a selectively erasable image refresh memory (BW) which enables graphic representations to be made on a screen (BS) by means of a stylus (SY) or of a light pen (LG). <IMAGE>
