The article begins with historical information about the time of the commencement of work of the Scientific-production Associantion «Sibcvetmetavtomatika» to create radio geodetic complex (RGC) «Krabik-B» (predecessor modification of «Krabik-BM»), the mention of the founders of the principle of action of this complex and the appointment RGC; is a picture of the ship station. The article provides information on the development of RGC «Krabik-BM» to provide a marine seismic survey, transfer it to new components and serial production. The authors of the report shows the need for modernization, the RGC and the proposed directions of modernization for significant improvement of a number of technical parameters. Offers technical solutions to increase the accuracy of the measurement range, optimized solutions specific navigation tasks, a significant increase the number of COP working in the area of the same OS, expansion options for placement of the OS, quick detection, identification and synchronization, implementation, communication between stations, increase over the horizon range, improved noise immunity, improve the quality of testing methods in the manufacture, improvement of operational properties RGC.
