NEW MEASURING SYSTEM FOR SEA TRIALS-SHIP SPEED AND POSITION MEASURING SYSTEM (TRIPOSIK) USING ULTRA-HIGH FREQUENCY RADIO WAVES-PARTS 1 AND 2

The radio wave equipment described in depth in this paper is intended for automatic collection and processing of ship speed trials and manoeuvrability data. Key equipment functions--listed as radio wave position measuring function, ship speed measuring function, and magnetic tape recording function--are discussed in detail with indication of UH frequencies used. The procedure adopted for evaluation of equipment performance and accuracy are presented. Prior to application of the equipment, two shore bases must be established. Recommendations on conduct of sea trials with the aid of the equipment and provision of radio wave interference countermeasures are noted. To test the equipment's overall accuracy, marine and shore tests were run. This procedure involved a comparison of the performance of the equipment described with data obtained using conventional measured mile marks. A long-distance arrival stability test was also conducted. Magnetic tape recordings and other trials are analysed ashore using the TRIAS programs run on a general-purpose computer. Components of the analytical system are outlined together with example of some analytical results produced by it. Order from: BSRA as No. 46,997.
