ZUBR气垫船磁罗经自差的岸基校正

摘要

分析利用传统"爱利法"在海上校正ZUBR气垫船磁罗经自差存在的航向保持困难、船磁随装载变化及经济成本高等问题.根据ZUBR气垫船可在陆地运动的特性,提出一种在岸基条件下校正该型气垫船磁罗经自差的方法.构建具体的磁罗经自差校正场环境模型,进而研究利用该校正场校正磁罗经自差的具体方法.研究成果对开展气垫船磁罗经自差校正工作具有实际意义.%The limitations of the Airy method for magnetic compass correction on 'ZUBR' air cushion vehicle are analyzed.The major problems are the following: It is hard to hold the required heading;the compass deviation is subject to the loading condition of the vehicle;the cost is too high.The on-land solution of magnetic compass correction is proposed by the land travel ability of the 'ZUBR' air cushion vehicle.The model of the test field for deviation compensation is built, and the correction procedure is investigated.The suggested method is of value for the deviation correction of compasses on other air cushion vehicles.
