FIELD: navigational instrumentation engineering. SUBSTANCE: compass-pickup has binnacle, deviation devices, airtight pot positioned in binnacle and filled with compass liquid. Magnetic sensing element is installed in pot on support, and induction converter is secured on pot. Waterproof structural assembly is positioned in lower part of binnacle. This assembly includes excitation generator, induction converter and amplifier-converter of induction converter output signals. Compass-pickup forms information of vessel magnetic course in the shape of DC signals the voltages of which are proportional to sine and cosine of magnetic course. EFFECT: more reliable functioning. 1 dwg
