摘要
罗经用于指示船舶、舰艇、火箭等运动载体在水平面内相对地球基准方向。与传统的电罗经和磁罗经相比,GPS罗经是一种新型的电子导航罗经,它集合了GPS与INS测姿技术,具有更多的优点。叙述了GPS罗经的组成原理及发展现状,详细阐述了GPS罗经的三维测姿原理,并给出了算法流程,针对现有的研究现状和技术难点,分析了其发展趋势。
Compass is used for indicating the reference direction opposite to earth in horizontal plane of some motion carriers, for example ships, naval vessels, rockets and so on. Compared with traditional compasses, magnetic compass and electric compass, GPS compass is one new kind of electronic navigation compass, which assembles technologies of GPS and INS, and has more advantages. The formation, principle and development situation of GPS compass are introduced, its attitude measurement principle and arithmetic progress are presented, and its development tendency based on current research situation and technology difficulty are analyzed.
