摘　　要：提出一种基于磁天线的罗兰C测向定位方法,建立测向定位模型,采用平面近似方法,结合球面三角形定理,解算出舰船概位,再利用牛顿迭代法对概位进行修正,得到舰船真实位置。以我国南海海域罗兰C台链为参照,分析算法的误差性能及工作区内的定位精度,验证该方法的可行性。A novel technique of direction and location for Loran-C based on magnetic antenna was proposed. A posttion fixing model was built up, probable location could be obtained by applying plane approximate method and spherical triangle theorem. The real location of ship can be gained when probable location is modified by Newton＇s iterative technique. Referred to Loran-C launcher of the south sea area in China, locating precision and error performance of the algorithm in the specific area was analyzed. The results showed that the technique is effective and feasible.
